* Cherry-pick from upstream:
- [CVE-2023-28531] ssh-add(1): when adding smartcard keys to
ssh-agent(1) with the per-hop destination constraints (ssh-add -h ...)
added in OpenSSH 8.9, a logic error prevented the constraints from
being communicated to the agent. This resulted in the keys being added
without constraints. The common cases of non-smartcard keys and keys
without destination constraints are unaffected. This problem was
reported by Luci Stanescu (closes: #1033166).
- [CVE-2023-48795] ssh(1), sshd(8): implement protocol extensions to
thwart the so-called "Terrapin attack" discovered by Fabian Bäumer,
Marcus Brinkmann and Jörg Schwenk. This attack allows a MITM to effect
a limited break of the integrity of the early encrypted SSH transport
protocol by sending extra messages prior to the commencement of
encryption, and deleting an equal number of consecutive messages
immediately after encryption starts. A peer SSH client/server would
not be able to detect that messages were deleted.
- [CVE-2023-51384] ssh-agent(1): when adding PKCS#11-hosted private keys
while specifying destination constraints, if the PKCS#11 token
returned multiple keys then only the first key had the constraints
applied. Use of regular private keys, FIDO tokens and unconstrained
keys are unaffected.
- [CVE-2023-51385] ssh(1): if an invalid user or hostname that contained
shell metacharacters was passed to ssh(1), and a ProxyCommand,
LocalCommand directive or "match exec" predicate referenced the user
or hostname via %u, %h or similar expansion token, then an attacker
who could supply arbitrary user/hostnames to ssh(1) could potentially
perform command injection depending on what quoting was present in the
user-supplied ssh_config(5) directive. ssh(1) now bans most shell
metacharacters from user and hostnames supplied via the command-line.

openssh (1:9.2p1-1) unstable; urgency=medium
* Set "UsePAM yes" when running regression tests, to match our default
sshd configuration.
* Ignore Lintian error about depending on lsb-base for now, to avoid
problems with partial upgrades on non-default init systems.
* New upstream release (https://www.openssh.com/releasenotes.html#9.2p1):
- [SECURITY] sshd(8): fix a pre-authentication double-free memory fault
introduced in OpenSSH 9.1. This is not believed to be exploitable, and
it occurs in the unprivileged pre-auth process that is subject to
chroot(2) and is further sandboxed on most major platforms.
- [SECURITY] ssh(8): in OpenSSH releases after 8.7, the PermitRemoteOpen
option would ignore its first argument unless it was one of the
special keywords "any" or "none", causing the permission list to fail
open if only one permission was specified.
- [SECURITY] ssh(1): if the CanonicalizeHostname and
CanonicalizePermittedCNAMEs options were enabled, and the system/libc
resolver did not check that names in DNS responses were valid, then
use of these options could allow an attacker with control of DNS to
include invalid characters (possibly including wildcards) in names
added to known_hosts files when they were updated. These names would
still have to match the CanonicalizePermittedCNAMEs allow-list, so
practical exploitation appears unlikely.
- ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that
controls whether the client-side ~C escape sequence that provides a
command-line is available. Among other things, the ~C command-line
could be used to add additional port-forwards at runtime. This option
defaults to "no", disabling the ~C command-line that was previously
enabled by default.
- sshd(8): add support for channel inactivity timeouts via a new
sshd_config(5) ChannelTimeout directive. This allows channels that
have not seen traffic in a configurable interval to be automatically
closed. Different timeouts may be applied to session, X11, agent and
TCP forwarding channels.
- sshd(8): add a sshd_config UnusedConnectionTimeout option to terminate
client connections that have no open channels for a length of time.
This complements the ChannelTimeout option above.
- sshd(8): add a -V (version) option to sshd like the ssh client has.
- ssh(1): add a "Host" line to the output of ssh -G showing the original
hostname argument. bz3343
- scp(1), sftp(1): add a -X option to both scp(1) and sftp(1) to allow
control over some SFTP protocol parameters: the copy buffer length and
the number of in-flight requests, both of which are used during
upload/download. Previously these could be controlled in sftp(1) only.
This makes them available in both SFTP protocol clients using the same
option character sequence.
- ssh-keyscan(1): allow scanning of complete CIDR address ranges, e.g.
"ssh-keyscan 192.168.0.0/24". If a CIDR range is passed, then it will
be expanded to all possible addresses in the range including the
all-0s and all-1s addresses.
- ssh(1): support dynamic remote port forwarding in escape
command-line's -R processing.
- ssh(1): when restoring non-blocking mode to stdio fds, restore exactly
the flags that ssh started with and don't just clobber them with zero,
as this could also remove the append flag from the set.
- ssh(1): avoid printf("%s", NULL) if using UserKnownHostsFile=none and
a hostkey in one of the system known hosts file changes.
- scp(1): switch scp from using pipes to a socket-pair for communication
with its ssh sub-processes, matching how sftp(1) operates.
- sshd(8): clear signal mask early in main(); sshd may have been started
with one or more signals masked (sigprocmask(2) is not cleared on
fork/exec) and this could interfere with various things, e.g. the
login grace timer. Execution environments that fail to clear the
signal mask before running sshd are clearly broken, but apparently
they do exist.
- ssh(1): warn if no host keys for hostbased auth can be loaded.
- sshd(8): Add server debugging for hostbased auth that is queued and
sent to the client after successful authentication, but also logged to
assist in diagnosis of HostbasedAuthentication problems.
- ssh(1): document use of the IdentityFile option as being usable to
list public keys as well as private keys.
- sshd(8): check for and disallow MaxStartups values less than or equal
to zero during config parsing, rather than failing later at runtime.
- ssh-keygen(1): fix parsing of hex cert expiry times specified on the
command-line when acting as a CA.
- scp(1): when scp(1) is using the SFTP protocol for transport (the
default), better match scp/rcp's handling of globs that don't match
the globbed characters but do match literally (e.g. trying to transfer
a file named "foo.[1]"). Previously scp(1) in SFTP mode would not
match these pathnames but legacy scp/rcp mode would.
- ssh-agent(1): document the "-O no-restrict-websafe" command-line
option.
- ssh(1): honour user's umask(2) if it is more restrictive then the ssh
default (022).
- sshd(8): allow writev(2) in the Linux seccomp sandbox. This seems to
be used by recent glibcs at least in some configurations during error
conditions.
- sshd(8): simplify handling of SSH_CONNECTION PAM env var, removing
global variable and checking the return value from pam_putenv.
- sshd(8): disable SANDBOX_SECCOMP_FILTER_DEBUG that was mistakenly
enabled during the OpenSSH 9.1 release cycle.
- sshd(8): defer PRNG seeding until after the initial closefrom(2) call.
PRNG seeding will initialize OpenSSL, and some engine providers (e.g.
Intel's QAT) will open descriptors for their own use that closefrom(2)
could clobber.

* New upstream release (https://www.openssh.com/releasenotes.html#9.1p1,
closes: #1021585):
- ssh-keyscan(1): fix a one-byte overflow in SSH- banner processing.
- ssh-keygen(1): double free() in error path of file hashing step in
signing/verify code.
- ssh-keysign(8): double-free in error path introduced in openssh-8.9.
- ssh(1), sshd(8): SetEnv directives in ssh_config and sshd_config are
now first-match-wins to match other directives. Previously if an
environment variable was multiply specified the last set value would
have been used.
- ssh-keygen(8): ssh-keygen -A (generate all default host key types)
will no longer generate DSA keys, as these are insecure and have not
been used by default for some years.
- ssh(1), sshd(8): add a RequiredRSASize directive to set a minimum RSA
key length. Keys below this length will be ignored for user
authentication and for host authentication in sshd(8). ssh(1) will
terminate a connection if the server offers an RSA key that falls
below this limit, as the SSH protocol does not include the ability to
retry a failed key exchange.
- sftp-server(8): add a "users-groups-by-id@openssh.com" extension
request that allows the client to obtain user/group names that
correspond to a set of uids/gids.
- sftp(1): use "users-groups-by-id@openssh.com" sftp-server extension
(when available) to fill in user/group names for directory listings.
- sftp-server(8): support the "home-directory" extension request defined
in draft-ietf-secsh-filexfer-extensions-00. This overlaps a bit with
the existing "expand-path@openssh.com", but some other clients support
it.
- ssh-keygen(1), sshd(8): allow certificate validity intervals, sshsig
verification times and authorized_keys expiry-time options to accept
dates in the UTC time zone in addition to the default of interpreting
them in the system time zone. YYYYMMDD and YYMMDDHHMM[SS] dates/times
will be interpreted as UTC if suffixed with a 'Z' character. Also
allow certificate validity intervals to be specified in raw
seconds-since-epoch as hex value, e.g. -V 0x1234:0x4567890. This is
intended for use by regress tests and other tools that call ssh-keygen
as part of a CA workflow.
- sftp(1): allow arguments to the sftp -D option, e.g. sftp -D
"/usr/libexec/sftp-server -el debug3".
- ssh-keygen(1): allow the existing -U (use agent) flag to work with "-Y
sign" operations, where it will be interpreted to require that the
private keys is hosted in an agent.
- ssh-keygen(1): implement the "verify-required" certificate option.
This was already documented when support for user-verified FIDO keys
was added, but the ssh-keygen(1) code was missing.
- ssh-agent(1): hook up the restrict_websafe command-line flag;
previously the flag was accepted but never actually used.
- sftp(1): improve filename tab completions: never try to complete names
to non-existent commands, and better match the completion type (local
or remote filename) against the argument position being completed.
- ssh-keygen(1), ssh(1), ssh-agent(1): several fixes to FIDO key
handling, especially relating to keys that request user-verification.
These should reduce the number of unnecessary PIN prompts for keys
that support intrinsic user verification.
- ssh-keygen(1): when enrolling a FIDO resident key, check if a
credential with matching application and user ID strings already
exists and, if so, prompt the user for confirmation before overwriting
the credential.
- sshd(8): improve logging of errors when opening authorized_keys files.
- ssh(1): avoid multiplexing operations that could cause SIGPIPE from
causing the client to exit early.
- ssh_config(5), sshd_config(5): clarify that the RekeyLimit directive
applies to both transmitted and received data.
- ssh-keygen(1): avoid double fclose() in error path.
- sshd(8): log an error if pipe() fails while accepting a connection.
- ssh-keyscan(1): add missing *-sk types to ssh-keyscan manpage.
- sshd(8): ensure that authentication passwords are cleared from memory
in error paths.
- ssh(1), ssh-agent(1): avoid possibility of notifier code executing
kill(-1).
- ssh_config(5): note that the ProxyJump directive also accepts the same
tokens as ProxyCommand.
- scp(1): do not ftruncate(3) files early when in sftp mode. The
previous behaviour of unconditionally truncating the destination file
would cause "scp ~/foo localhost:foo" and the reverse "scp
localhost:foo ~/foo" to delete all the contents of their destination.
- ssh-keygen(1): improve error message when 'ssh-keygen -Y sign' is
unable to load a private key.
- sftp(1), scp(1): when performing operations that glob(3) a remote
path, ensure that the implicit working directory used to construct
that path escapes glob(3) characters. This prevents glob characters
from being processed in places they shouldn't, e.g. "cd /tmp/a*/",
"get *.txt" should have the get operation treat the path "/tmp/a*"
literally and not attempt to expand it (LP: #1483751).
- ssh(1), sshd(8): be stricter in which characters will be accepted in
specifying a mask length; allow only 0-9.
- ssh-keygen(1): avoid printing hash algorithm twice when dumping a KRL.
- ssh(1), sshd(8): continue running local I/O for open channels during
SSH transport rekeying. This should make ~-escapes work in the client
(e.g. to exit) if the connection happened to have stalled during a
rekey event.
- ssh(1), sshd(8): avoid potential poll() spin during rekeying.
- Further hardening for sshbuf internals: disallow "reparenting" a
hierarchical sshbuf and zero the entire buffer if reallocation fails.
- sshd(8): add AUDIT_ARCH_PPC to supported seccomp sandbox
architectures.

openssh (1:9.0p1-1) unstable; urgency=medium
* New upstream release (https://www.openssh.com/releasenotes.html#9.0p1):
- scp(1): Use the SFTP protocol by default (closes: #144579, #204546,
#327019). This changes scp's quoting semantics by no longer performing
wildcard expansion using the remote shell, and (with some server
versions) no longer expanding ~user paths. The -O option is available
to use the old protocol. See NEWS.Debian for more details.
- ssh(1), sshd(8): use the hybrid Streamlined NTRU Prime + x25519 key
exchange method by default ("sntrup761x25519-sha512@openssh.com").
The NTRU algorithm is believed to resist attacks enabled by future
quantum computers and is paired with the X25519 ECDH key exchange (the
previous default) as a backstop against any weaknesses in NTRU Prime
that may be discovered in the future. The combination ensures that the
hybrid exchange offers at least as good security as the status quo.
- sftp-server(8): support the "copy-data" extension to allow server-
side copying of files/data, following the design in
draft-ietf-secsh-filexfer-extensions-00.
- sftp(1): add a "cp" command to allow the sftp client to perform
server-side file copies.
- ssh(1), sshd(8): upstream: fix poll(2) spin when a channel's output fd
closes without data in the channel buffer (closes: #1007822).
- sshd(8): pack pollfd array in server listen/accept loop. Could cause
the server to hang/spin when MaxStartups > RLIMIT_NOFILE.
- ssh-keygen(1): avoid NULL deref via the find-principals and
check-novalidate operations. bz3409 and GHPR307 respectively.
- scp(1): fix a memory leak in argument processing.
- sshd(8): don't try to resolve ListenAddress directives in the sshd
re-exec path. They are unused after re-exec and parsing errors
(possible for example if the host's network configuration changed)
could prevent connections from being accepted.
- sshd(8): when refusing a public key authentication request from a
client for using an unapproved or unsupported signature algorithm
include the algorithm name in the log message to make debugging
easier.
- ssh(1), sshd(8): Fix possible integer underflow in scan_scaled(3)
parsing of K/M/G/etc quantities.
- sshd(8): default to not using sandbox when cross compiling. On most
systems poll(2) does not work when the number of FDs is reduced with
setrlimit, so assume it doesn't when cross compiling and we can't run
the test.

openssh (1:8.9p1-1) unstable; urgency=medium
* New upstream release (https://www.openssh.com/releasenotes.html#8.9p1):
- sshd(8): fix an integer overflow in the user authentication path that,
in conjunction with other logic errors, could have yielded
unauthenticated access under difficult to exploit conditions.
- sshd(8), portable OpenSSH only: this release removes in-built support
for MD5-hashed passwords.
- ssh(1), sshd(8), ssh-add(1), ssh-agent(1): add a system for
restricting forwarding and use of keys added to ssh-agent(1).
- ssh(1), sshd(8): add the sntrup761x25519-sha512@openssh.com hybrid
ECDH/x25519 + Streamlined NTRU Prime post-quantum KEX to the default
KEXAlgorithms list (after the ECDH methods but before the prime-group
DH ones). The next release of OpenSSH is likely to make this key
exchange the default method.
- ssh-keygen(1): when downloading resident keys from a FIDO token, pass
back the user ID that was used when the key was created and append it
to the filename the key is written to (if it is not the default).
Avoids keys being clobbered if the user created multiple resident keys
with the same application string but different user IDs.
- ssh-keygen(1), ssh(1), ssh-agent(1): better handling for FIDO keys on
tokens that provide user verification (UV) on the device itself,
including biometric keys, avoiding unnecessary PIN prompts.
- ssh-keygen(1): add "ssh-keygen -Y match-principals" operation to
perform matching of principals names against an allowed signers file.
To be used towards a TOFU model for SSH signatures in git.
- ssh-add(1), ssh-agent(1): allow pin-required FIDO keys to be added to
ssh-agent(1). $SSH_ASKPASS will be used to request the PIN at
authentication time.
- ssh-keygen(1): allow selection of hash at sshsig signing time (either
sha512 (default) or sha256).
- ssh(1), sshd(8): read network data directly to the packet input buffer
instead indirectly via a small stack buffer. Provides a modest
performance improvement.
- ssh(1), sshd(8): read data directly to the channel input buffer,
providing a similar modest performance improvement.
- ssh(1): extend the PubkeyAuthentication configuration directive to
accept yes|no|unbound|host-bound to allow control over one of the
protocol extensions used to implement agent-restricted keys.
- sshd(8): document that CASignatureAlgorithms, ExposeAuthInfo and
PubkeyAuthOptions can be used in a Match block.
- sshd(8): fix possible string truncation when constructing paths to
.rhosts/.shosts files with very long user home directory names.
- ssh-keysign(1): unbreak for KEX algorithms that use SHA384/512
exchange hashes.
- ssh(1): don't put the TTY into raw mode when SessionType=none, avoids
^C being unable to kill such a session.
- scp(1): fix some corner-case bugs in SFTP-mode handling of ~-prefixed
paths.
- ssh(1): unbreak hostbased auth using RSA keys. Allow ssh(1) to select
RSA keys when only RSA/SHA2 signature algorithms are configured (this
is the default case). Previously RSA keys were not being considered in
the default case.
- ssh-keysign(1): make ssh-keysign use the requested signature algorithm
and not the default for the key type. Part of unbreaking hostbased
auth for RSA/SHA2 keys.
- ssh(1): stricter UpdateHostkey signature verification logic on the
client-side. Require RSA/SHA2 signatures for RSA hostkeys except when
RSA/SHA1 was explicitly negotiated during initial KEX.
- ssh(1), sshd(8): fix signature algorithm selection logic for
UpdateHostkeys on the server side. The previous code tried to prefer
RSA/SHA2 for hostkey proofs of RSA keys, but missed some cases. This
will use RSA/SHA2 signatures for RSA keys if the client proposed these
algorithms in initial KEX.
- All: convert all uses of select(2)/pselect(2) to poll(2)/ppoll(2).
This includes the mainloops in ssh(1), ssh-agent(1), ssh-agent(1) and
sftp-server(8), as well as the sshd(8) listen loop and all other FD
read/writability checks. On platforms with missing or broken
poll(2)/ppoll(2) syscalls a select(2)-based compat shim is available.
- ssh-keygen(1): the "-Y find-principals" command was verifying key
validity when using ca certs but not with simple key lifetimes within
the allowed signers file.
- ssh-keygen(1): make sshsig verify-time argument parsing optional.
- sshd(8): fix truncation in rhosts/shosts path construction.
- ssh(1), ssh-agent(1): avoid xmalloc(0) for PKCS#11 keyid for ECDSA
keys (we already did this for RSA keys). Avoids fatal errors for
PKCS#11 libraries that return empty keyid, e.g. Microchip ATECC608B
"cryptoauthlib".
- ssh(1), ssh-agent(1): improve the testing of credentials against
inserted FIDO: ask the token whether a particular key belongs to it in
cases where the token supports on-token user-verification (e.g.
biometrics) rather than just assuming that it will accept it. Will
reduce spurious "Confirm user presence" notifications for key handles
that relate to FIDO keys that are not currently inserted in at least
some cases.
- ssh(1), sshd(8): correct value for IPTOS_DSCP_LE. It needs to allow
for the preceding two ECN bits.
- ssh-keygen(1): add missing -O option to usage() for the "-Y sign"
option.
- ssh-keygen(1): fix a NULL deref when using the find-principals
function, when matching an allowed_signers line that contains a
namespace restriction, but no restriction specified on the
command-line
- ssh-agent(1): fix memleak in process_extension().
- ssh(1): suppress "Connection to xxx closed" messages when LogLevel is
set to "error" or above.
- ssh(1), sshd(8): use correct zlib flags when inflate(3)-ing compressed
packet data.
- scp(1): when recursively transferring files in SFTP mode, create the
destination directory if it doesn't already exist to match scp(1) in
legacy RCP mode behaviour.
- scp(1): many improvements in error message consistency between scp(1)
in SFTP mode vs legacy RCP mode.
- sshd(8): fix potential race in SIGTERM handling.
- ssh(1), ssh(8): since DSA keys are deprecated, move them to the end of
the default list of public keys so that they will be tried last.
- ssh-keygen(1): allow 'ssh-keygen -Y find-principals' to match wildcard
principals in allowed_signers files.
- ssh(1), sshd(8): don't trust closefrom(2) on Linux. glibc's
implementation does not work in a chroot when the kernel does not have
close_range(2). It tries to read from /proc/self/fd and when that
fails dies with an assertion of sorts. Instead, call close_range(2)
directly from our compat code and fall back if that fails.
- Correct handling of exceptfds/POLLPRI in our select(2)-based
poll(2)/ppoll(2) compat implementation.

* New upstream release (https://www.openssh.com/releasenotes.html#8.8p1,
closes: #996391):
- This release disables RSA signatures using the SHA-1 hash algorithm by
default. (Existing RSA keys may still be used and do not need to be
replaced; see NEWS.Debian if you have problems connecting to old SSH
servers.)
- ssh(1): allow the ssh_config(5) CanonicalizePermittedCNAMEs directive
to accept a "none" argument to specify the default behaviour.
- scp(1): when using the SFTP protocol, continue transferring files
after a transfer error occurs, better matching original scp/rcp
behaviour.
- ssh(1): fixed a number of memory leaks in multiplexing,
- ssh-keygen(1): avoid crash when using the -Y find-principals command.
- A number of documentation and manual improvements.
- ssh(1)/sshd(8): some fixes to the pselect(2) replacement compatibility
code.
* Work around missing RSA SHA-2 signature support in conch until the
upstream fix lands in Debian.

openssh (1:8.7p1-1) unstable; urgency=medium
* debian/upstream/signing-key.asc: Update from upstream.
* New upstream release (https://www.openssh.com/releasenotes.html#8.7p1):
- scp(1): this release changes the behaviour of remote to remote copies
(e.g. "scp host-a:/path host-b:") to transfer through the local host
by default (closes: #734386, LP: #1462758). This was previously
available via the -3 flag. A -R flag has been added to select the old
behaviour.
- ssh(1)/sshd(8): both the client and server are now using a stricter
configuration file parser.
- ssh(1): when using SSHFP DNS records for host key verification, ssh(1)
will verify all matching records instead of just those with the
specific signature type requested.
- ssh-keygen(1): when generating a FIDO key and specifying an explicit
attestation challenge (using -Ochallenge), the challenge will now be
hashed by the builtin security key middleware.
- sshd(8): environment="..." directives in authorized_keys files are now
first-match-wins and limited to 1024 discrete environment variable
names.
- scp(1): experimental support for transfers using the SFTP protocol as
a replacement for the venerable SCP/RCP protocol that it has
traditionally used. SFTP offers more predictable filename handling and
does not require expansion of glob(3) patterns via the shell on the
remote side.
SFTP support may be enabled via a temporary scp -s flag. It is
intended for SFTP to become the default transfer mode in the near
future, at which time the -s flag will be removed. The -O flag exists
to force use of the original SCP/RCP protocol for cases where SFTP may
be unavailable or incompatible.
- sftp-server(8): add a protocol extension to support expansion of ~/
and ~user/ prefixed paths. This was added to support these paths when
used by scp(1) while in SFTP mode.
- ssh(1): add a ForkAfterAuthentication ssh_config(5) counterpart to the
ssh(1) -f flag. GHPR231
- ssh(1): add a StdinNull directive to ssh_config(5) that allows the
config file to do the same thing as -n does on the ssh(1) command-
line. GHPR231
- ssh(1): add a SessionType directive to ssh_config, allowing the
configuration file to offer equivalent control to the -N (no session)
and -s (subsystem) command-line flags (closes: #609122).
- ssh-keygen(1): allowed signers files used by ssh-keygen(1) signatures
now support listing key validity intervals alongside they key, and
ssh-keygen(1) can optionally check during signature verification
whether a specified time falls inside this interval. This feature is
intended for use by git to support signing and verifying objects using
ssh keys.
- ssh-keygen(8): support printing of the full public key in a sshsig
signature via a -Oprint-pubkey flag.
- ssh(1)/sshd(8): start time-based re-keying exactly on schedule in the
client and server mainloops. Previously the re-key timeout could
expire but re-keying would not start until a packet was sent or
received, causing a spin in select() if the connection was quiescent.
- ssh-keygen(1): avoid Y2038 problem in printing certificate validity
lifetimes. Dates past 2^31-1 seconds since epoch were displayed
incorrectly on some platforms.
- scp(1): allow spaces to appear in usernames for local to remote and
scp -3 remote to remote copies.
- ssh(1)/sshd(8): remove references to ChallengeResponseAuthentication
in favour of KbdInteractiveAuthentication. The former is what was in
SSHv1, the latter is what is in SSHv2 (RFC4256) and they were treated
as somewhat but not entirely equivalent. We retain the old name as a
deprecated alias so configuration files continue to work as well as a
reference in the man page for people looking for it.
- ssh(1)/ssh-add(1)/ssh-keygen(1): fix decoding of X.509 subject name
when extracting a key from a PKCS#11 certificate.
- ssh(1): restore blocking status on stdio fds before close. ssh(1)
needs file descriptors in non-blocking mode to operate but it was not
restoring the original state on exit. This could cause problems with
fds shared with other programs via the shell.
- ssh(1)/sshd(8): switch both client and server mainloops from select(3)
to pselect(3). Avoids race conditions where a signal may arrive
immediately before select(3) and not be processed until an event
fires.
- ssh(1): sessions started with ControlPersist were incorrectly
executing a shell when the -N (no shell) option was specified (closes:
#762633).
- ssh(1): check if IPQoS or TunnelDevice are already set before
overriding. Prevents values in config files from overriding values
supplied on the command line.
- ssh(1): fix debug message when finding a private key to match a
certificate being attempted for user authentication. Previously it
would print the certificate's path, whereas it was supposed to be
showing the private key's path.
- sshd(8): match host certificates against host public keys, not private
keys. Allows use of certificates with private keys held in a
ssh-agent.
- ssh(1): add a workaround for a bug in OpenSSH 7.4 sshd(8), which
allows RSA/SHA2 signatures for public key authentication but fails to
advertise this correctly via SSH2_MSG_EXT_INFO. This causes clients of
these server to incorrectly match PubkeyAcceptedAlgorithms and
potentially refuse to offer valid keys.
- sftp(1)/scp(1): degrade gracefully if a sftp-server offers the
limits@openssh.com extension but fails when the client tries to invoke
it.
- ssh(1): allow ssh_config SetEnv to override $TERM, which is otherwise
handled specially by the protocol. Useful in ~/.ssh/config to set TERM
to something generic (e.g. "xterm" instead of "xterm-256color") for
destinations that lack terminfo entries.
- sftp-server(8): the limits@openssh.com extension was incorrectly
marked as an operation that writes to the filesystem, which made it
unavailable in sftp-server read-only mode.
- ssh(1): fix SEGV in UpdateHostkeys debug() message, triggered when the
update removed more host keys than remain present.
- Many manual page fixes.
- sshd(8): handle GIDs > 2^31 in getgrouplist. When compiled in 32bit
mode, the getgrouplist implementation may fail for GIDs greater than
LONG_MAX.
- ssh(1): xstrdup environment variable used by ForwardAgent.
- sshd(8): don't sigdie() in signal handler in privsep child process;
this can end up causing sandbox violations.
* New upstream release (https://www.openssh.com/releasenotes.html#8.6p1):
- sftp-server(8): add a new limits@openssh.com protocol extension that
allows a client to discover various server limits, including maximum
packet size and maximum read/write length.
- sftp(1): use the new limits@openssh.com extension (when available) to
select better transfer lengths in the client.
- sshd(8): Add ModuliFile keyword to sshd_config to specify the location
of the "moduli" file containing the groups for DH-GEX.
- ssh_config(5), sshd_config(5): sync CASignatureAlgorithms lists in
manual pages with the current default.
- ssh(1): ensure that pkcs11_del_provider() is called before exit.
- ssh(1), sshd(8): fix problems in string->argv conversion. Multiple
backslashes were not being dequoted correctly and quoted space in the
middle of a string was being incorrectly split.
- ssh(1): return non-zero exit status when killed by signal.
- sftp-server(8): increase maximum SSH2_FXP_READ to match the maximum
packet size. Also handle zero-length reads that are not explicitly
banned by the spec.
- sshd(8): don't mistakenly exit on transient read errors on the network
socket (e.g. EINTR, EAGAIN).
- Create a dedicated contrib/gnome-ssk-askpass3.c source instead of
building it from the same file as used for GNOME2. Use the GNOME3
gdk_seat_grab() to manage keyboard/mouse/server grabs for better
compatibility with Wayland.
- sshd(8): soft-disallow the fstatat64 syscall in the Linux seccomp-bpf
sandbox.
* New upstream release (https://www.openssh.com/releasenotes.html#8.5p1):
- ssh(1), sshd(8): change the first-preference signature algorithm from
ECDSA to ED25519.
- ssh(1), sshd(8): set the TOS/DSCP specified in the configuration for
interactive use prior to TCP connect.
- ssh(1), sshd(8): remove the pre-standardization cipher
rijndael-cbc@lysator.liu.se.
- ssh(1), sshd(8): update/replace the experimental post-quantum hybrid
key exchange method based on Streamlined NTRU Prime coupled with
X25519.
- ssh(1): disable CheckHostIP by default. It provides insignificant
benefits while making key rotation significantly more difficult,
especially for hosts behind IP-based load-balancers (closes: #764027).
- ssh(1): enable UpdateHostkeys by default subject to some conservative
preconditions (closes: #875532):
+ The key was matched in the UserKnownHostsFile (and not in the
GlobalKnownHostsFile).
+ The same key does not exist under another name.
+ A certificate host key is not in use.
+ known_hosts contains no matching wildcard hostname pattern.
+ VerifyHostKeyDNS is not enabled.
+ The default UserKnownHostsFile is in use.
We expect some of these conditions will be modified or relaxed in
future.
- ssh(1), sshd(8): add a new LogVerbose configuration directive that
allows forcing maximum debug logging by file/function/line
pattern-lists.
- ssh(1): when prompting the user to accept a new hostkey, display any
other host names/addresses already associated with the key.
- ssh(1): allow UserKnownHostsFile=none to indicate that no known_hosts
file should be used to identify host keys.
- ssh(1): add a ssh_config KnownHostsCommand option that allows the
client to obtain known_hosts data from a command in addition to the
usual files.
- ssh(1): add a ssh_config PermitRemoteOpen option that allows the
client to restrict the destination when RemoteForward is used with
SOCKS.
- ssh(1): for FIDO keys, if a signature operation fails with a
"incorrect PIN" reason and no PIN was initially requested from the
user, then request a PIN and retry the operation. This supports some
biometric devices that fall back to requiring PIN when reading of the
biometric failed, and devices that require PINs for all hosted
credentials.
- sshd(8): implement client address-based rate-limiting via new
sshd_config(5) PerSourceMaxStartups and PerSourceNetBlockSize
directives that provide more fine-grained control on a per-origin
address basis than the global MaxStartups limit.
- ssh(1): Prefix keyboard interactive prompts with "(user@host)" to make
it easier to determine which connection they are associated with in
cases like scp -3, ProxyJump, etc. (closes: #343267).
- sshd(8): fix sshd_config SetEnv directives located inside Match
blocks.
- ssh(1): when requesting a FIDO token touch on stderr, inform the user
once the touch has been recorded.
- ssh(1): prevent integer overflow when ridiculously large
ConnectTimeout values are specified, capping the effective value (for
most platforms) at 24 days.
- ssh(1): consider the ECDSA key subtype when ordering host key
algorithms in the client.
- ssh(1), sshd(8): rename the PubkeyAcceptedKeyTypes keyword to
PubkeyAcceptedAlgorithms. The previous name incorrectly suggested that
it control allowed key algorithms, when this option actually specifies
the signature algorithms that are accepted. The previous name remains
available as an alias (closes: #933665).
- ssh(1), sshd(8): similarly, rename HostbasedKeyTypes (ssh) and
HostbasedAcceptedKeyTypes (sshd) to HostbasedAcceptedAlgorithms.
- sftp-server(8): add missing lsetstat@openssh.com documentation and
advertisement in the server's SSH2_FXP_VERSION hello packet.
- ssh(1), sshd(8): more strictly enforce KEX state-machine by banning
packet types once they are received. Fixes memleak caused by duplicate
SSH2_MSG_KEX_DH_GEX_REQUEST.
- sftp(1): allow the full range of UIDs/GIDs for chown/chgrp on 32bit
platforms instead of being limited by LONG_MAX.
- Minor man page fixes (capitalization, commas, etc.)
- sftp(1): when doing an sftp recursive upload or download of a
read-only directory, ensure that the directory is created with write
and execute permissions in the interim so that the transfer can
actually complete, then set the directory permission as the final
step.
- ssh-keygen(1): document the -Z, check the validity of its argument
earlier and provide a better error message if it's not correct.
- ssh(1): ignore comments at the end of config lines in ssh_config,
similar to what we already do for sshd_config.
- sshd_config(5): mention that DisableForwarding is valid in a
sshd_config Match block.
- sftp(1): fix incorrect sorting of "ls -ltr" under some circumstances.
- ssh(1), sshd(8): fix potential integer truncation of (unlikely)
timeout values.
- ssh(1): make hostbased authentication send the signature algorithm in
its SSH2_MSG_USERAUTH_REQUEST packets instead of the key type. This
make HostbasedAcceptedAlgorithms do what it is supposed to - filter on
signature algorithm and not key type.
- sshd(8): add a number of platform-specific syscalls to the Linux
seccomp-bpf sandbox.
- sshd(8): remove debug message from sigchld handler that could cause
deadlock on some platforms.
- Sync contrib/ssh-copy-id with upstream.
* Remove OpenBSD-specific rdomain references from sshd_config(5) (closes:
#998069).
* Define MAXHOSTNAMELEN on GNU/Hurd (thanks, Svante Signell; closes:
#997030).
* Build-depend on libelogind-dev as an alternative to libsystemd-dev on
Linux (thanks, Svante Signell; closes: #997035).
* Backport from upstream:
- CVE-2021-41617 (closes: #995130): sshd(8) from OpenSSH 6.2 through 8.7
failed to correctly initialise supplemental groups when executing an
AuthorizedKeysCommand or AuthorizedPrincipalsCommand, where a
AuthorizedKeysCommandUser or AuthorizedPrincipalsCommandUser directive
has been set to run the command as a different user. Instead these
commands would inherit the groups that sshd(8) was started with.
* Configure with ac_cv_func_closefrom=no to avoid an incompatibility with
glibc 2.34's fallback_closefrom function (thanks, William 'jawn-smith'
Wilson; LP: #1944621).

openssh (1:8.4p1-1) unstable; urgency=medium
* New upstream release (https://www.openssh.com/txt/release-8.4):
- [SECURITY] ssh-agent(1): restrict ssh-agent from signing web
challenges for FIDO/U2F keys.
- [SECURITY] ssh-keygen(1): Enable FIDO 2.1 credProtect extension when
generating a FIDO resident key.
- ssh-keygen(1): the format of the attestation information optionally
recorded when a FIDO key is generated has changed. It now includes the
authenticator data needed to validate attestation signatures.
- The API between OpenSSH and the FIDO token middleware has changed and
the SSH_SK_VERSION_MAJOR version has been incremented as a result.
Third-party middleware libraries must support the current API version
(7) to work with OpenSSH 8.4.
- ssh(1), ssh-keygen(1): support for FIDO keys that require a PIN for
each use. These keys may be generated using ssh-keygen using a new
"verify-required" option. When a PIN-required key is used, the user
will be prompted for a PIN to complete the signature operation.
- sshd(8): authorized_keys now supports a new "verify-required" option
to require FIDO signatures assert that the token verified that the
user was present before making the signature. The FIDO protocol
supports multiple methods for user-verification, but currently OpenSSH
only supports PIN verification.
- sshd(8), ssh-keygen(1): add support for verifying FIDO webauthn
signatures. Webauthn is a standard for using FIDO keys in web
browsers. These signatures are a slightly different format to plain
FIDO signatures and thus require explicit support.
- ssh(1): allow some keywords to expand shell-style ${ENV} environment
variables. The supported keywords are CertificateFile, ControlPath,
IdentityAgent and IdentityFile, plus LocalForward and RemoteForward
when used for Unix domain socket paths.
- ssh(1), ssh-agent(1): allow some additional control over the use of
ssh-askpass via a new $SSH_ASKPASS_REQUIRE environment variable,
including forcibly enabling and disabling its use (closes: #368657).
- ssh(1): allow ssh_config(5)'s AddKeysToAgent keyword accept a time
limit for keys in addition to its current flag options. Time-limited
keys will automatically be removed from ssh-agent after their expiry
time has passed.
- scp(1), sftp(1): allow the -A flag to explicitly enable agent
forwarding in scp and sftp. The default remains to not forward an
agent, even when ssh_config enables it.
- ssh(1): add a '%k' TOKEN that expands to the effective HostKey of the
destination. This allows, e.g., keeping host keys in individual files
using "UserKnownHostsFile ~/.ssh/known_hosts.d/%k" (closes: #481250).
- ssh(1): add %-TOKEN, environment variable and tilde expansion to the
UserKnownHostsFile directive, allowing the path to be completed by the
configuration.
- ssh-keygen(1): allow "ssh-add -d -" to read keys to be deleted from
stdin.
- sshd(8): improve logging for MaxStartups connection throttling. sshd
will now log when it starts and stops throttling and periodically
while in this state.
- ssh(1), ssh-keygen(1): better support for multiple attached FIDO
tokens. In cases where OpenSSH cannot unambiguously determine which
token to direct a request to, the user is now required to select a
token by touching it. In cases of operations that require a PIN to be
verified, this avoids sending the wrong PIN to the wrong token and
incrementing the token's PIN failure counter (tokens effectively erase
their keys after too many PIN failures).
- sshd(8): fix Include before Match in sshd_config (LP: #1885990).
- ssh(1): close stdin/out/error when forking after authentication
completes ("ssh -f ...").
- ssh(1), sshd(8): limit the amount of channel input data buffered,
avoiding peers that advertise large windows but are slow to read from
causing high memory consumption.
- ssh-agent(1): handle multiple requests sent in a single write() to the
agent.
- sshd(8): allow sshd_config longer than 256k.
- sshd(8): avoid spurious "Unable to load host key" message when sshd
load a private key but no public counterpart.
- ssh(1): prefer the default hostkey algorithm list whenever we have a
hostkey that matches its best-preference algorithm.
- sshd(1): when ordering the hostkey algorithms to request from a
server, prefer certificate types if the known_hosts files contain a
key marked as a @cert-authority.
- ssh(1): perform host key fingerprint comparisons for the "Are you sure
you want to continue connecting (yes/no/[fingerprint])?" prompt with
case sensitivity.
- sshd(8): ensure that address/masklen mismatches in sshd_config yield
fatal errors at daemon start time rather than later when they are
evaluated.
- ssh-keygen(1): ensure that certificate extensions are lexically
sorted. Previously if the user specified a custom extension then the
everything would be in order except the custom ones.
- ssh(1): also compare username when checking for JumpHost loops.
- ssh-keygen(1): preserve group/world read permission on known_hosts
files across runs of "ssh-keygen -Rf /path". The old behaviour was to
remove all rights for group/other.
- ssh-keygen(1): Mention the [-a rounds] flag in the ssh-keygen manual
page and usage().
- sshd(8): explicitly construct path to ~/.ssh/rc rather than relying on
it being relative to the current directory, so that it can still be
found if the shell startup changes its directory.
- sshd(8): when redirecting sshd's log output to a file, undo this
redirection after the session child process is forked(). Fixes missing
log messages when using this feature under some circumstances.
- sshd(8): start ClientAliveInterval bookkeeping before first pass
through select() loop; fixed theoretical case where busy sshd may
ignore timeouts from client.
- ssh(1): only reset the ServerAliveInterval check when we receive
traffic from the server and ignore traffic from a port forwarding
client, preventing a client from keeping a connection alive when it
should be terminated.
- ssh-keygen(1): avoid spurious error message when ssh-keygen creates
files outside ~/.ssh.
- sftp-client(1): fix off-by-one error that caused sftp downloads to
make one more concurrent request that desired. This prevented using
sftp(1) in unpipelined request/response mode, which is useful when
debugging.
- ssh(1), sshd(8): handle EINTR in waitfd() and timeout_connect()
helpers.
- ssh(1), ssh-keygen(1): defer creation of ~/.ssh until we attempt to
write to it so we don't leave an empty .ssh directory when it's not
needed.
- ssh(1), sshd(8): fix multiplier when parsing time specifications when
handling seconds after other units.
- sshd(8): always send any PAM account messages. If the PAM account
stack returns any messages, always send them to the user and not just
if the check succeeds.
- gnome-ssh-askpass3: ensure the "close" button is not focused by
default for SSH_ASKPASS_PROMPT=none prompts. Avoids space/enter
accidentally dismissing FIDO touch notifications.
- gnome-ssh-askpass3: allow some control over textarea colour via
$GNOME_SSH_ASKPASS_FG_COLOR and $GNOME_SSH_ASKPASS_BG_COLOR
environment variables.
- Detect the Frankenstein monster of Linux/X32 and allow the sandbox to
function there.

openssh (1:8.3p1-1) unstable; urgency=medium
* New upstream release (https://www.openssh.com/txt/release-8.3):
- [SECURITY] scp(1): when receiving files, scp(1) could become
desynchronised if a utimes(2) system call failed. This could allow
file contents to be interpreted as file metadata and thereby permit an
adversary to craft a file system that, when copied with scp(1) in a
configuration that caused utimes(2) to fail (e.g. under a SELinux
policy or syscall sandbox), transferred different file names and
contents to the actual file system layout.
- sftp(1): reject an argument of "-1" in the same way as ssh(1) and
scp(1) do instead of accepting and silently ignoring it.
- sshd(8): make IgnoreRhosts a tri-state option: "yes" to ignore
rhosts/shosts, "no" to allow rhosts/shosts or (new) "shosts-only" to
allow .shosts files but not .rhosts.
- sshd(8): allow the IgnoreRhosts directive to appear anywhere in a
sshd_config, not just before any Match blocks.
- ssh(1): add %TOKEN percent expansion for the LocalForward and
RemoteForward keywords when used for Unix domain socket forwarding.
- all: allow loading public keys from the unencrypted envelope of a
private key file if no corresponding public key file is present.
- ssh(1), sshd(8): prefer to use chacha20 from libcrypto where possible
instead of the (slower) portable C implementation included in OpenSSH.
- ssh-keygen(1): add ability to dump the contents of a binary key
revocation list via "ssh-keygen -lQf /path".
- ssh(1): fix IdentitiesOnly=yes to also apply to keys loaded from a
PKCS11Provider.
- ssh-keygen(1): avoid NULL dereference when trying to convert an
invalid RFC4716 private key.
- scp(1): when performing remote-to-remote copies using "scp -3", start
the second ssh(1) channel with BatchMode=yes enabled to avoid
confusing and non-deterministic ordering of prompts.
- ssh(1), ssh-keygen(1): when signing a challenge using a FIDO token,
perform hashing of the message to be signed in the middleware layer
rather than in OpenSSH code. This permits the use of security key
middlewares that perform the hashing implicitly, such as Windows
Hello.
- ssh(1): fix incorrect error message for "too many known hosts files."
- ssh(1): make failures when establishing "Tunnel" forwarding terminate
the connection when ExitOnForwardFailure is enabled.
- ssh-keygen(1): fix printing of fingerprints on private keys and add a
regression test for same.
- sshd(8): document order of checking AuthorizedKeysFile (first) and

- sshd(8): document that /etc/hosts.equiv and /etc/shosts.equiv are not
considered for HostbasedAuthentication when the target user is root.
- ssh(1), ssh-keygen(1): fix NULL dereference in private certificate key
parsing.
- ssh(1), sshd(8): more consistency between sets of %TOKENS are accepted
in various configuration options.
- ssh(1), ssh-keygen(1): improve error messages for some common PKCS#11
C_Login failure cases.
- ssh(1), sshd(8): make error messages for problems during SSH banner
exchange consistent with other SSH transport-layer error messages and
ensure they include the relevant IP addresses.
- ssh-keygen(1), ssh-add(1): when downloading FIDO2 resident keys from a
token, don't prompt for a PIN until the token has told us that it
needs one. Avoids double-prompting on devices that implement
on-device authentication (closes: #932071).
- sshd(8), ssh-keygen(1): no-touch-required FIDO certificate option
should be an extension, not a critical option.
- ssh(1), ssh-keygen(1), ssh-add(1): offer a better error message when
trying to use a FIDO key function and SecurityKeyProvider is empty.
- ssh-add(1), ssh-agent(8): ensure that a key lifetime fits within the

attempts to set one at process start time rather than fatally erroring

openssh (1:8.2p1-1) unstable; urgency=medium
* New upstream release (https://www.openssh.com/txt/release-8.2, closes:
#951582):
- ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa"
(RSA/SHA1) algorithm from those accepted for certificate signatures
(i.e. the client and server CASignatureAlgorithms option) and will use
the rsa-sha2-512 signature algorithm by default when the ssh-keygen(1)
CA signs new certificates.
- ssh(1), sshd(8): Remove diffie-hellman-group14-sha1 from the default
key exchange proposal for both the client and server.
- ssh-keygen(1): The command-line options related to the generation and
screening of safe prime numbers used by the
diffie-hellman-group-exchange-* key exchange algorithms have changed.
Most options have been folded under the -O flag.
- sshd(8): The sshd listener process title visible to ps(1) has changed
to include information about the number of connections that are
currently attempting authentication and the limits configured by
MaxStartups.
- Add support for FIDO/U2F hardware authenticators.
- ssh-keygen(1): Add a "no-touch-required" option when generating
FIDO-hosted keys, that disables their default behaviour of requiring a
physical touch/tap on the token during authentication. Note: not all
tokens support disabling the touch requirement.
- sshd(8): Add a sshd_config PubkeyAuthOptions directive that collects
miscellaneous public key authentication-related options for sshd(8).
At present it supports only a single option "no-touch-required". This
causes sshd to skip its default check for FIDO/U2F keys that the
signature was authorised by a touch or press event on the token
hardware.
- ssh(1), sshd(8), ssh-keygen(1): Add a "no-touch-required" option for
authorized_keys and a similar extension for certificates. This option
disables the default requirement that FIDO key signatures attest that
the user touched their key to authorize them, mirroring the similar
PubkeyAuthOptions sshd_config option.
- ssh-keygen(1): Add support for the writing the FIDO attestation
information that is returned when new keys are generated via the "-O
write-attestation=/path" option. FIDO attestation certificates may be
used to verify that a FIDO key is hosted in trusted hardware. OpenSSH
does not currently make use of this information, beyond optionally
writing it to disk.
- Add support for FIDO2 resident keys.
- sshd(8): Add an Include sshd_config keyword that allows including
additional configuration files via glob(3) patterns (closes: #631189).
- ssh(1)/sshd(8): Make the LE (low effort) DSCP code point available via
the IPQoS directive.
- ssh(1): When AddKeysToAgent=yes is set and the key contains no
comment, add the key to the agent with the key's path as the comment.
- ssh-keygen(1), ssh-agent(1): Expose PKCS#11 key labels and X.509
subjects as key comments, rather than simply listing the PKCS#11
provider library path.
- ssh-keygen(1): Allow PEM export of DSA and ECDSA keys.
- sshd(8): When clients get denied by MaxStartups, send a notification
prior to the SSH2 protocol banner according to RFC4253 section 4.2
(closes: #275458).
- ssh(1), ssh-agent(1): When invoking the $SSH_ASKPASS prompt program,
pass a hint to the program to describe the type of desired prompt.
The possible values are "confirm" (indicating that a yes/no
confirmation dialog with no text entry should be shown), "none" (to
indicate an informational message only), or blank for the original
ssh-askpass behaviour of requesting a password/phrase.
- ssh(1): Allow forwarding a different agent socket to the path
specified by $SSH_AUTH_SOCK, by extending the existing ForwardAgent
option to accepting an explicit path or the name of an environment
variable in addition to yes/no.
- ssh-keygen(1): Add a new signature operations "find-principals" to
look up the principal associated with a signature from an
allowed-signers file.
- sshd(8): Expose the number of currently-authenticating connections
along with the MaxStartups limit in the process title visible to "ps".
- sshd(8): Make ClientAliveCountMax=0 have sensible semantics: it will
now disable connection killing entirely rather than the current
behaviour of instantly killing the connection after the first liveness
test regardless of success.
- sshd(8): Clarify order of AllowUsers / DenyUsers vs AllowGroups /
DenyGroups in the sshd(8) manual page.
- sshd(8): Better describe HashKnownHosts in the manual page.
- sshd(8): Clarify that that permitopen=/PermitOpen do no name or
address translation in the manual page.
- sshd(8): Allow the UpdateHostKeys feature to function when multiple
known_hosts files are in use. When updating host keys, ssh will now
search subsequent known_hosts files, but will add updated host keys to
the first specified file only.
- All: Replace all calls to signal(2) with a wrapper around
sigaction(2). This wrapper blocks all other signals during the
handler preventing races between handlers, and sets SA_RESTART which
should reduce the potential for short read/write operations.
- sftp(1): Fix a race condition in the SIGCHILD handler that could turn
in to a kill(-1).
- sshd(8): Fix a case where valid (but extremely large) SSH channel IDs
were being incorrectly rejected.
- ssh(1): When checking host key fingerprints as answers to new hostkey
prompts, ignore whitespace surrounding the fingerprint itself.
- All: Wait for file descriptors to be readable or writeable during
non-blocking connect, not just readable. Prevents a timeout when the
server doesn't immediately send a banner (e.g. multiplexers like
sslh).
- sshd_config(5): Document the sntrup4591761x25519-sha512@tinyssh.org
key exchange algorithm.
* Add more historical md5sums of /etc/ssh/sshd_config between 1:7.4p1-1
and 1:7.8p1-1 inclusive (closes: #951220).
* ssh(1): Explain that -Y is equivalent to -X in the default configuration
(closes: #951640).
* Include /etc/ssh/ssh_config.d/*.conf from /etc/ssh/ssh_config and
/etc/ssh/sshd_config.d/*.conf from /etc/ssh/sshd_config (closes:

openssh (1:8.1p1-1) unstable; urgency=medium
* New upstream release (https://www.openssh.com/txt/release-8.1):
- ssh(1), sshd(8), ssh-agent(1): Add protection for private keys at rest
in RAM against speculation and memory side-channel attacks like
Spectre, Meltdown and Rambleed. This release encrypts private keys
when they are not in use with a symmetric key that is derived from a
relatively large "prekey" consisting of random data (currently 16KB).
- ssh(1): Allow %n to be expanded in ProxyCommand strings.
- ssh(1), sshd(8): Allow prepending a list of algorithms to the default
set by starting the list with the '^' character, e.g.
"HostKeyAlgorithms ^ssh-ed25519".
- ssh-keygen(1): Add an experimental lightweight signature and
verification ability. Signatures may be made using regular ssh keys
held on disk or stored in a ssh-agent and verified against an
authorized_keys-like list of allowed keys. Signatures embed a
namespace that prevents confusion and attacks between different usage
domains (e.g. files vs email).
- ssh-keygen(1): Print key comment when extracting public key from a
private key.
- ssh-keygen(1): Accept the verbose flag when searching for host keys in
known hosts (i.e. "ssh-keygen -vF host") to print the matching host's
random-art signature too.
- All: Support PKCS8 as an optional format for storage of private keys
to disk. The OpenSSH native key format remains the default, but PKCS8
is a superior format to PEM if interoperability with non-OpenSSH
software is required, as it may use a less insecure key derivation
function than PEM's.
- ssh(1): If a PKCS#11 token returns no keys then try to login and
refetch them.
- ssh(1): Produce a useful error message if the user's shell is set
incorrectly during "match exec" processing.
- sftp(1): Allow the maximum uint32 value for the argument passed to -b
which allows better error messages from later validation.
- ssh-keyscan(1): Include SHA2-variant RSA key algorithms in KEX
proposal; allows ssh-keyscan to harvest keys from servers that disable
old SHA1 ssh-rsa.
- sftp(1): Print explicit "not modified" message if a file was requested
for resumed download but was considered already complete.
- sftp(1): Fix a typo and make <esc><right> move right to the closest
end of a word just like <esc><left> moves left to the closest
beginning of a word.
- sshd(8): Cap the number of permitopen/permitlisten directives allowed
to appear on a single authorized_keys line.
- All: Fix a number of memory leaks (one-off or on exit paths).
- ssh(1), sshd(8): Check for convtime() refusing to accept times that
resolve to LONG_MAX.
- ssh(1): Slightly more instructive error message when the user
specifies multiple -J options on the command-line (closes: #929669).
- ssh-agent(1): Process agent requests for RSA certificate private keys
using correct signature algorithm when requested.
- sftp(1): Check for user@host when parsing sftp target. This allows
user@[1.2.3.4] to work without a path.
- sshd(8): Enlarge format buffer size for certificate serial number so
the log message can record any 64-bit integer without truncation.
- sshd(8): For PermitOpen violations add the remote host and port to be
able to more easily ascertain the source of the request. Add the same
logging for PermitListen violations which were not previously logged
at all.
- scp(1), sftp(1): Use the correct POSIX format style for left
justification for the transfer progress meter.
- sshd(8): When examining a configuration using sshd -T, assume any
attribute not provided by -C does not match, which allows it to work
when sshd_config contains a Match directive with or without -C.
- ssh(1), ssh-keygen(1): Downgrade PKCS#11 "provider returned no slots"
warning from log level error to debug. This is common when attempting
to enumerate keys on smartcard readers with no cards plugged in.
- ssh(1), ssh-keygen(1): Do not unconditionally log in to PKCS#11
tokens. Avoids spurious PIN prompts for keys not selected for
authentication in ssh(1) and when listing public keys available in a
token using ssh-keygen(1).
- ssh(1), sshd(8): Fix typo that prevented detection of Linux VRF.
- sshd(8): In the Linux seccomp-bpf sandbox, allow mprotect(2) with
PROT_(READ|WRITE|NONE) only. This syscall is used by some hardened
heap allocators.
- sshd(8): In the Linux seccomp-bpf sandbox, allow the s390-specific
ioctl for ECC hardware support.
* Re-enable hardening on hppa, since the corresponding GCC bug is
apparently fixed.

* New upstream release (https://www.openssh.com/txt/release-8.0, closes:
#927792):
- ssh(1), ssh-agent(1), ssh-add(1): Add support for ECDSA keys in
PKCS#11 tokens (LP: #1665695).
- ssh(1), sshd(8): Add experimental quantum-computing resistant key
exchange method, based on a combination of Streamlined NTRU Prime
4591^761 and X25519.
- ssh-keygen(1): Increase the default RSA key size to 3072 bits,
following NIST Special Publication 800-57's guidance for a 128-bit
equivalent symmetric security level (LP: #1445625).
- ssh(1): Allow "PKCS11Provider=none" to override later instances of the
PKCS11Provider directive in ssh_config.
- sshd(8): Add a log message for situations where a connection is
dropped for attempting to run a command but a sshd_config
ForceCommand=internal-sftp restriction is in effect.
- ssh(1): When prompting whether to record a new host key, accept the
key fingerprint as a synonym for "yes". This allows the user to paste
a fingerprint obtained out of band at the prompt and have the client
do the comparison for you.
- ssh-keygen(1): When signing multiple certificates on a single
command-line invocation, allow automatically incrementing the
certificate serial number.
- scp(1), sftp(1): Accept -J option as an alias to ProxyJump on the scp
and sftp command-lines.
- ssh-agent(1), ssh-pkcs11-helper(8), ssh-add(1): Accept "-v"
command-line flags to increase the verbosity of output; pass verbose
flags though to subprocesses, such as ssh-pkcs11-helper started from
ssh-agent.
- ssh-add(1): Add a "-T" option to allowing testing whether keys in an
agent are usable by performing a signature and a verification.
- sftp-server(8): Add a "lsetstat@openssh.com" protocol extension that
replicates the functionality of the existing SSH2_FXP_SETSTAT
operation but does not follow symlinks.
- sftp(1): Add "-h" flag to chown/chgrp/chmod commands to request they
do not follow symlinks.
- sshd(8): Expose $SSH_CONNECTION in the PAM environment. This makes
the connection 4-tuple available to PAM modules that wish to use it in
decision-making.
- sshd(8): Add a ssh_config "Match final" predicate. Matches in same
pass as "Match canonical" but doesn't require hostname
canonicalisation be enabled.
- sftp(1): Support a prefix of '@' to suppress echo of sftp batch
commands.
- ssh-keygen(1): When printing certificate contents using "ssh-keygen
-Lf /path/certificate", include the algorithm that the CA used to sign
the cert.
- sshd(8): Fix authentication failures when sshd_config contains
"AuthenticationMethods any" inside a Match block that overrides a more
restrictive default.
- sshd(8): Avoid sending duplicate keepalives when ClientAliveCount is
enabled.
- sshd(8): Fix two race conditions related to SIGHUP daemon restart.
Remnant file descriptors in recently-forked child processes could
block the parent sshd's attempt to listen(2) to the configured
addresses. Also, the restarting parent sshd could exit before any
child processes that were awaiting their re-execution state had
completed reading it, leaving them in a fallback path.
- ssh(1): Fix stdout potentially being redirected to /dev/null when
ProxyCommand=- was in use.
- sshd(8): Avoid sending SIGPIPE to child processes if they attempt to
write to stderr after their parent processes have exited.
- ssh(1): Fix bad interaction between the ssh_config ConnectTimeout and
ConnectionAttempts directives - connection attempts after the first
were ignoring the requested timeout (LP: #1798049).
- ssh-keyscan(1): Return a non-zero exit status if no keys were found
(closes: #374980, LP: #1661745).
- scp(1): Sanitize scp filenames to allow UTF-8 characters without
terminal control sequences.
- sshd(8): Fix confusion between ClientAliveInterval and time-based
RekeyLimit that could cause connections to be incorrectly closed.
- ssh(1), ssh-add(1): Correct some bugs in PKCS#11 token PIN handling at
initial token login. The attempt to read the PIN could be skipped in
some cases, particularly on devices with integrated PIN readers. This
would lead to an inability to retrieve keys from these tokens.
- ssh(1), ssh-add(1): Support keys on PKCS#11 tokens that set the
CKA_ALWAYS_AUTHENTICATE flag by requring a fresh login after the
C_SignInit operation.
- ssh(1): Improve documentation for ProxyJump/-J, clarifying that local
configuration does not apply to jump hosts.
- ssh-keygen(1): Clarify manual - ssh-keygen -e only writes public keys,
not private.
- ssh(1), sshd(8): be more strict in processing protocol banners,
allowing \r characters only immediately before \n.
- Various: fix a number of memory leaks.
- scp(1), sftp(1): fix calculation of initial bandwidth limits. Account
for bytes written before the timer starts and adjust the schedule on
which recalculations are performed. Avoids an initial burst of
traffic and yields more accurate bandwidth limits.
- sshd(8): Only consider the ext-info-c extension during the initial key
eschange. It shouldn't be sent in subsequent ones, but if it is
present we should ignore it. This prevents sshd from sending a
SSH_MSG_EXT_INFO for REKEX for these buggy clients.
- ssh-keygen(1): Clarify manual that ssh-keygen -F (find host in
authorized_keys) and -R (remove host from authorized_keys) options may
accept either a bare hostname or a [hostname]:port combo.
- ssh(1): Don't attempt to connect to empty SSH_AUTH_SOCK.
- sshd(8): Silence error messages when sshd fails to load some of the
default host keys. Failure to load an explicitly-configured hostkey
is still an error, and failure to load any host key is still fatal.
- ssh(1): Redirect stderr of ProxyCommands to /dev/null when ssh is
started with ControlPersist; prevents random ProxyCommand output from
interfering with session output.
- ssh(1): The ssh client was keeping a redundant ssh-agent socket
(leftover from authentication) around for the life of the connection.
- sshd(8): Fix bug in HostbasedAcceptedKeyTypes and
PubkeyAcceptedKeyTypes options. If only RSA-SHA2 signature types were
specified, then authentication would always fail for RSA keys as the
monitor checks only the base key (not the signature algorithm) type
against *AcceptedKeyTypes.
- ssh(1): Request correct signature types from ssh-agent when
certificate keys and RSA-SHA2 signatures are in use.
- sshd(8): Don't set $MAIL if UsePAM=yes as PAM typically specifies the
user environment if it's enabled (closes: #189920, #532754).
* Mostly resynced GSSAPI key exchange patch with Fedora. Major changes:
- Support selection of GSSAPI key exchange algorithms.
- Support GSSAPI key exchange methods with DH and SHA2.
- Support GSSAPI key exchange using ECDH and SHA2.

openssh (1:7.9p1-1) unstable; urgency=medium
* New upstream release (https://www.openssh.com/txt/release-7.9):
- ssh(1), sshd(8): allow most port numbers to be specified using service
names from getservbyname(3) (typically /etc/services; closes:
#177406).
- ssh(1): allow the IdentityAgent configuration directive to accept
environment variable names. This supports the use of multiple agent
sockets without needing to use fixed paths.
- sshd(8): support signalling sessions via the SSH protocol. A limited
subset of signals is supported and only for login or command sessions
(i.e. not subsystems) that were not subject to a forced command via
authorized_keys or sshd_config.
- ssh(1): support "ssh -Q sig" to list supported signature options.
Also "ssh -Q help" to show the full set of supported queries.
- ssh(1), sshd(8): add a CASignatureAlgorithms option for the client and
server configs to allow control over which signature formats are
allowed for CAs to sign certificates. For example, this allows
banning CAs that sign certificates using the RSA-SHA1 signature
algorithm.
- sshd(8), ssh-keygen(1): allow key revocation lists (KRLs) to revoke
keys specified by SHA256 hash.
- ssh-keygen(1): allow creation of key revocation lists directly from
base64-encoded SHA256 fingerprints. This supports revoking keys using
only the information contained in sshd(8) authentication log messages.
- ssh(1), ssh-keygen(1): avoid spurious "invalid format" errors when
attempting to load PEM private keys while using an incorrect
passphrase.
- sshd(8): when a channel closed message is received from a client,
close the stderr file descriptor at the same time stdout is closed.
This avoids stuck processes if they were waiting for stderr to close
and were insensitive to stdin/out closing (closes: #844494).
- ssh(1): allow ForwardX11Timeout=0 to disable the untrusted X11
forwarding timeout and support X11 forwarding indefinitely.
Previously the behaviour of ForwardX11Timeout=0 was undefined.
- sshd(8): when compiled with GSSAPI support, cache supported method
OIDs regardless of whether GSSAPI authentication is enabled in the
main section of sshd_config. This avoids sandbox violations if GSSAPI
authentication was later enabled in a Match block.
- sshd(8): do not fail closed when configured with a text key revocation
list that contains a too-short key.
- ssh(1): treat connections with ProxyJump specified the same as ones
with a ProxyCommand set with regards to hostname canonicalisation
(i.e. don't try to canonicalise the hostname unless
CanonicalizeHostname is set to 'always').
- ssh(1): fix regression in OpenSSH 7.8 that could prevent public-key
authentication using certificates hosted in a ssh-agent(1) or against
sshd(8) from OpenSSH <7.8 (LP: #1790963).
- All: support building against the openssl-1.1 API (releases 1.1.0g and
later). The openssl-1.0 API will remain supported at least until
OpenSSL terminates security patch support for that API version
(closes: #828475).
- sshd(8): allow the futex(2) syscall in the Linux seccomp sandbox;
apparently required by some glibc/OpenSSL combinations.
* Remove dh_builddeb override to use xz compression; this has been the
default since dpkg 1.17.0.
* Simplify debian/rules using /usr/share/dpkg/default.mk.
* Remove /etc/network/if-up.d/openssh-server, as it causes more problems
than it solves (thanks, Christian Ehrhardt, Andreas Hasenack, and David
Britton; closes: #789532, LP: #1037738, #1674330, #1718227). Add an
"if-up hook removed" section to README.Debian documenting the corner
case that may need configuration adjustments.

openssh (1:7.8p1-1) unstable; urgency=medium
* New upstream release (https://www.openssh.com/txt/release-7.8, closes:
#907534):
- ssh-keygen(1): Write OpenSSH format private keys by default instead of
using OpenSSL's PEM format (closes: #905407). The OpenSSH format,
supported in OpenSSH releases since 2014 and described in the
PROTOCOL.key file in the source distribution, offers substantially
better protection against offline password guessing and supports key
comments in private keys. If necessary, it is possible to write old
PEM-style keys by adding "-m PEM" to ssh-keygen's arguments when
generating or updating a key.
- sshd(8): Remove internal support for S/Key multiple factor
authentication. S/Key may still be used via PAM or BSD auth.
- ssh(1): Remove vestigial support for running ssh(1) as setuid. This
used to be required for hostbased authentication and the (long gone)
rhosts-style authentication, but has not been necessary for a long
time. Attempting to execute ssh as a setuid binary, or with uid !=
effective uid will now yield a fatal error at runtime.
- sshd(8): The semantics of PubkeyAcceptedKeyTypes and the similar
HostbasedAcceptedKeyTypes options have changed. These now specify
signature algorithms that are accepted for their respective
authentication mechanism, where previously they specified accepted key
types. This distinction matters when using the RSA/SHA2 signature
algorithms "rsa-sha2-256", "rsa-sha2-512" and their certificate
counterparts. Configurations that override these options but omit
these algorithm names may cause unexpected authentication failures (no
action is required for configurations that accept the default for
these options).
- sshd(8): The precedence of session environment variables has changed.
~/.ssh/environment and environment="..." options in authorized_keys
files can no longer override SSH_* variables set implicitly by sshd.
- ssh(1)/sshd(8): The default IPQoS used by ssh/sshd has changed. They
will now use DSCP AF21 for interactive traffic and CS1 for bulk. For
a detailed rationale, please see the commit message:
https://cvsweb.openbsd.org/src/usr.bin/ssh/readconf.c#rev1.284
- ssh(1)/sshd(8): Add new signature algorithms "rsa-sha2-256-cert-
v01@openssh.com" and "rsa-sha2-512-cert-v01@openssh.com" to explicitly
force use of RSA/SHA2 signatures in authentication.
- sshd(8): Extend the PermitUserEnvironment option to accept a whitelist
of environment variable names in addition to global "yes" or "no"
settings.
- sshd(8): Add a PermitListen directive to sshd_config(5) and a
corresponding permitlisten= authorized_keys option that control which
listen addresses and port numbers may be used by remote forwarding
(ssh -R ...).
- sshd(8): Add some countermeasures against timing attacks used for
account validation/enumeration. sshd will enforce a minimum time or
each failed authentication attempt consisting of a global 5ms minimum
plus an additional per-user 0-4ms delay derived from a host secret.
- sshd(8): Add a SetEnv directive to allow an administrator to
explicitly specify environment variables in sshd_config. Variables
set by SetEnv override the default and client-specified environment.
- ssh(1): Add a SetEnv directive to request that the server sets an
environment variable in the session. Similar to the existing SendEnv
option, these variables are set subject to server configuration.
- ssh(1): Allow "SendEnv -PATTERN" to clear environment variables
previously marked for sending to the server (closes: #573316).
- ssh(1)/sshd(8): Make UID available as a %-expansion everywhere that
the username is available currently.
- ssh(1): Allow setting ProxyJump=none to disable ProxyJump
functionality.
- sshd(8): Avoid observable differences in request parsing that could be
used to determine whether a target user is valid.
- ssh(1)/sshd(8): Fix some memory leaks.
- ssh(1): Fix a pwent clobber (introduced in openssh-7.7) that could
occur during key loading, manifesting as crash on some platforms.
- sshd_config(5): Clarify documentation for AuthenticationMethods
option.
- ssh(1): Ensure that the public key algorithm sent in a public key
SSH_MSG_USERAUTH_REQUEST matches the content of the signature blob.
Previously, these could be inconsistent when a legacy or non-OpenSSH
ssh-agent returned a RSA/SHA1 signature when asked to make a RSA/SHA2
signature.
- sshd(8): Fix failures to read authorized_keys caused by faulty
supplemental group caching.
- scp(1): Apply umask to directories, fixing potential mkdir/chmod race
when copying directory trees.
- ssh-keygen(1): Return correct exit code when searching for and hashing
known_hosts entries in a single operation.
- ssh(1): Prefer the ssh binary pointed to via argv[0] to $PATH when
re-executing ssh for ProxyJump.
- sshd(8): Do not ban PTY allocation when a sshd session is restricted
because the user password is expired as it breaks password change
dialog.
- ssh(1)/sshd(8): Fix error reporting from select() failures.
- ssh(1): Improve documentation for -w (tunnel) flag, emphasising that
-w implicitly sets Tunnel=point-to-point.
- ssh-agent(1): Implement EMFILE mitigation for ssh-agent. ssh-agent
will no longer spin when its file descriptor limit is exceeded.
- ssh(1)/sshd(8): Disable SSH2_MSG_DEBUG messages for Twisted Conch
clients. Twisted Conch versions that lack a version number in their
identification strings will mishandle these messages when running on
Python 2.x (https://twistedmatrix.com/trac/ticket/9422).
- sftp(1): Notify user immediately when underlying ssh process dies
expectedly.
- ssh(1)/sshd(8): Fix tunnel forwarding; regression in 7.7 release.
- ssh-agent(1): Don't kill ssh-agent's listening socket entirely if it
fails to accept(2) a connection.
- ssh(1): Add some missing options in the configuration dump output (ssh
-G).
- sshd(8): Expose details of completed authentication to PAM auth
modules via SSH_AUTH_INFO_0 in the PAM environment.
* Switch debian/watch to HTTPS.

openssh (1:7.7p1-1) unstable; urgency=medium
* New upstream release (https://www.openssh.com/txt/release-7.7):
- ssh(1)/sshd(8): Drop compatibility support for some very old SSH
implementations, including ssh.com <=2.* and OpenSSH <= 3.*. These
versions were all released in or before 2001 and predate the final SSH
RFCs. The support in question isn't necessary for RFC-compliant SSH
implementations.
- Add experimental support for PQC XMSS keys (Extended Hash-Based
Signatures).
- sshd(8): Add an "rdomain" criterion for the sshd_config Match keyword
to allow conditional configuration that depends on which routing
domain a connection was received on.
- sshd_config(5): Add an optional rdomain qualifier to the ListenAddress
directive to allow listening on different routing domains.
- sshd(8): Add "expiry-time" option for authorized_keys files to allow
for expiring keys.
- ssh(1): Add a BindInterface option to allow binding the outgoing
connection to an interface's address (basically a more usable
BindAddress; closes: #289592).
- ssh(1): Expose device allocated for tun/tap forwarding via a new %T
expansion for LocalCommand. This allows LocalCommand to be used to
prepare the interface.
- sshd(8): Expose the device allocated for tun/tap forwarding via a new
SSH_TUNNEL environment variable. This allows automatic setup of the
interface and surrounding network configuration automatically on the
server.
- ssh(1)/scp(1)/sftp(1): Add URI support to ssh, sftp and scp, e.g.
ssh://user@host or sftp://user@host/path. Additional connection
parameters described in draft-ietf-secsh-scp-sftp-ssh-uri-04 are not
implemented since the ssh fingerprint format in the draft uses the
deprecated MD5 hash with no way to specify any other algorithm.
- ssh-keygen(1): Allow certificate validity intervals that specify only
a start or stop time (instead of both or neither).
- sftp(1): Allow "cd" and "lcd" commands with no explicit path argument.
lcd will change to the local user's home directory as usual. cd will
change to the starting directory for session (because the protocol
offers no way to obtain the remote user's home directory).
- sshd(8): When doing a config test with sshd -T, only require the
attributes that are actually used in Match criteria rather than (an
incomplete list of) all criteria.
- ssh(1)/sshd(8): More strictly check signature types during key
exchange against what was negotiated. Prevents downgrade of RSA
signatures made with SHA-256/512 to SHA-1.
- sshd(8): Fix support for client that advertise a protocol version of
"1.99" (indicating that they are prepared to accept both SSHv1 and
SSHv2). This was broken in OpenSSH 7.6 during the removal of SSHv1
support.
- ssh(1): Warn when the agent returns a ssh-rsa (SHA1) signature when a
rsa-sha2-256/512 signature was requested. This condition is possible
when an old or non-OpenSSH agent is in use.
- ssh-agent(1): Fix regression introduced in 7.6 that caused ssh-agent
to fatally exit if presented an invalid signature request message.
- sshd_config(5): Accept yes/no flag options case-insensitively, as has
been the case in ssh_config(5) for a long time (LP: #1656557).
- ssh(1): Improve error reporting for failures during connection. Under
some circumstances misleading errors were being shown.
- ssh-keyscan(1): Add -D option to allow printing of results directly in
SSHFP format.
- ssh(1): Compatibility fix for some servers that erroneously drop the
connection when the IUTF8 (RFC8160) option is sent.
- scp(1): Disable RemoteCommand and RequestTTY in the ssh session
started by scp (sftp was already doing this).
- ssh-keygen(1): Refuse to create a certificate with an unusable number
of principals.
- ssh-keygen(1): Fatally exit if ssh-keygen is unable to write all the
public key during key generation. Previously it would silently ignore
errors writing the comment and terminating newline.
- ssh(1): Do not modify hostname arguments that are addresses by
automatically forcing them to lower-case. Instead canonicalise them
jo resolve ambiguities (e.g. ::0001 => ::1) before they are matched
against known_hosts.
- ssh(1): Don't accept junk after "yes" or "no" responses to hostkey
prompts.
- sftp(1): Have sftp print a warning about shell cleanliness when
decoding the first packet fails, which is usually caused by shells
polluting stdout of non-interactive startups.
- ssh(1)/sshd(8): Switch timers in packet code from using wall-clock
time to monotonic time, allowing the packet layer to better function
over a clock step and avoiding possible integer overflows during
steps.
- sshd(8): Correctly detect MIPS ABI in use at configure time. Fixes
sandbox violations on some environments.
- Build and link with "retpoline" flags when available to mitigate the
"branch target injection" style (variant 2) of the Spectre
branch-prediction vulnerability.

openssh (1:7.6p1-1) unstable; urgency=medium
* New upstream release (https://www.openssh.com/txt/release-7.6):
- CVE-2017-15906: sftp-server(8): In read-only mode, sftp-server was
incorrectly permitting creation of zero-length files. Reported by
Michal Zalewski.
- ssh(1): Delete SSH protocol version 1 support, associated
configuration options and documentation (LP: #1584321).
- ssh(1)/sshd(8): Remove support for the hmac-ripemd160 MAC.
- ssh(1)/sshd(8): Remove support for the arcfour, blowfish and CAST
ciphers.
- Refuse RSA keys <1024 bits in length and improve reporting for keys
that do not meet this requirement.
- ssh(1): Do not offer CBC ciphers by default.
- ssh(1): Add RemoteCommand option to specify a command in the ssh
config file instead of giving it on the client's command line. This
allows the configuration file to specify the command that will be
executed on the remote host.
- sshd(8): Add ExposeAuthInfo option that enables writing details of the
authentication methods used (including public keys where applicable)
to a file that is exposed via a $SSH_USER_AUTH environment variable in
the subsequent session.
- ssh(1): Add support for reverse dynamic forwarding. In this mode, ssh
will act as a SOCKS4/5 proxy and forward connections to destinations
requested by the remote SOCKS client. This mode is requested using
extended syntax for the -R and RemoteForward options and, because it
is implemented solely at the client, does not require the server be
updated to be supported.
- sshd(8): Allow LogLevel directive in sshd_config Match blocks.
- ssh-keygen(1): Allow inclusion of arbitrary string or flag certificate
extensions and critical options.
- ssh-keygen(1): Allow ssh-keygen to use a key held in ssh-agent as a CA
when signing certificates.
- ssh(1)/sshd(8): Allow IPQoS=none in ssh/sshd to not set an explicit
ToS/DSCP value and just use the operating system default.
- ssh-add(1): Add -q option to make ssh-add quiet on success.
- ssh(1): Expand the StrictHostKeyChecking option with two new settings.
The first "accept-new" will automatically accept hitherto-unseen keys
but will refuse connections for changed or invalid hostkeys. This is
a safer subset of the current behaviour of StrictHostKeyChecking=no.
The second setting "off", is a synonym for the current behaviour of
StrictHostKeyChecking=no: accept new host keys, and continue
connection for hosts with incorrect hostkeys. A future release will
change the meaning of StrictHostKeyChecking=no to the behaviour of
"accept-new".
- ssh(1): Add SyslogFacility option to ssh(1) matching the equivalent
option in sshd(8).
- ssh(1): Use HostKeyAlias if specified instead of hostname for matching
host certificate principal names.
- sftp(1): Implement sorting for globbed ls.
- ssh(1): Add a user@host prefix to client's "Permission denied"
messages, useful in particular when using "stacked" connections (e.g.
ssh -J) where it's not clear which host is denying.
- ssh(1): Accept unknown EXT_INFO extension values that contain \0
characters. These are legal, but would previously cause fatal
connection errors if received.
- sftp(1): Print '?' instead of incorrect link count (that the protocol
doesn't provide) for remote listings.
- ssh(1): Return failure rather than fatal() for more cases during
session multiplexing negotiations. Causes the session to fall back to
a non-mux connection if they occur.
- ssh(1): Mention that the server may send debug messages to explain
public key authentication problems under some circumstances.
- Translate OpenSSL error codes to better report incorrect passphrase
errors when loading private keys.
- sshd(8): Adjust compatibility patterns for WinSCP to correctly
identify versions that implement only the legacy DH group exchange
scheme (closes: #877800).
- ssh(1): Print the "Killed by signal 1" message only at LogLevel
verbose so that it is not shown at the default level; prevents it from
appearing during ssh -J and equivalent ProxyCommand configs.
- ssh-keygen(1): When generating all hostkeys (ssh-keygen -A), clobber
existing keys if they exist but are zero length. Zero-length keys
could previously be made if ssh-keygen failed or was interrupted part
way through generating them.
- ssh-keyscan(1): Avoid double-close() on file descriptors.
- sshd(8): Avoid reliance on shared use of pointers shared between
monitor and child sshd processes.
- sshd_config(8): Document available AuthenticationMethods.
- ssh(1): Avoid truncation in some login prompts.
- ssh(1): Make "--" before the hostname terminate argument processing
after the hostname too (closes: #873201).
- ssh-keygen(1): Switch from aes256-cbc to aes256-ctr for encrypting
new-style private keys.
- ssh(1): Warn and do not attempt to use keys when the public and
private halves do not match.
- sftp(1): Don't print verbose error message when ssh disconnects from
under sftp.
- sshd(8): Fix keepalive scheduling problem: prevent activity on a
forwarded port from preventing the keepalive from being sent.
- sshd(8): When started without root privileges, don't require the
privilege separation user or path to exist.
- ssh(1)/sshd(8): Correctness fix for channels implementation: accept
channel IDs greater than 0x7FFFFFFF.
- sshd(8): Expose list of completed authentication methods to PAM via
the SSH_AUTH_INFO_0 PAM environment variable.
- ssh(1)/sshd(8): Fix several problems in the tun/tap forwarding code,
mostly to do with host/network byte order confusion.

openssh (1:7.5p1-1) experimental; urgency=medium
* New upstream release (https://www.openssh.com/txt/release-7.5):
- SECURITY: ssh(1), sshd(8): Fix weakness in CBC padding oracle
countermeasures that allowed a variant of the attack fixed in OpenSSH
7.3 to proceed. Note that the OpenSSH client disables CBC ciphers by
default, sshd offers them as lowest-preference options and will remove
them by default entirely in the next release.
- This release deprecates the sshd_config UsePrivilegeSeparation option,
thereby making privilege separation mandatory (closes: #407754).
- The format of several log messages emitted by the packet code has
changed to include additional information about the user and their
authentication state. Software that monitors ssh/sshd logs may need
to account for these changes.
- ssh(1), sshd(8): Support "=-" syntax to easily remove methods from
algorithm lists, e.g. Ciphers=-*cbc.
- sshd(1): Fix NULL dereference crash when key exchange start messages
are sent out of sequence.
- ssh(1), sshd(8): Allow form-feed characters to appear in configuration
files.
- sshd(8): Fix regression in OpenSSH 7.4 support for the server-sig-algs
extension, where SHA2 RSA signature methods were not being correctly
advertised.
- ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs in
known_hosts processing.
- ssh(1): Allow ssh to use certificates accompanied by a private key
file but no corresponding plain *.pub public key.
- ssh(1): When updating hostkeys using the UpdateHostKeys option, accept
RSA keys if HostkeyAlgorithms contains any RSA keytype. Previously,
ssh could ignore RSA keys when only the ssh-rsa-sha2-* methods were
enabled in HostkeyAlgorithms and not the old ssh-rsa method.
- ssh(1): Detect and report excessively long configuration file lines.
- Merge a number of fixes found by Coverity and reported via Redhat and
FreeBSD. Includes fixes for some memory and file descriptor leaks in
error paths.
- ssh(1), sshd(8): When logging long messages to stderr, don't truncate
"\r\n" if the length of the message exceeds the buffer.
- ssh(1): Fully quote [host]:port in generated ProxyJump/-J command-
line; avoid confusion over IPv6 addresses and shells that treat square
bracket characters specially.
- Fix various fallout and sharp edges caused by removing SSH protocol 1
support from the server, including the server banner string being
incorrectly terminated with only \n (instead of \r\n), confusing error
messages from ssh-keyscan, and a segfault in sshd if protocol v.1 was
enabled for the client and sshd_config contained references to legacy
keys.
- ssh(1), sshd(8): Free fd_set on connection timeout.
- sftp(1): Fix division by zero crash in "df" output when server returns
zero total filesystem blocks/inodes.
- ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL errors
encountered during key loading to more meaningful error codes.
- ssh-keygen(1): Sanitise escape sequences in key comments sent to
printf but preserve valid UTF-8 when the locale supports it.
- ssh(1), sshd(8): Return reason for port forwarding failures where
feasible rather than always "administratively prohibited".
- sshd(8): Fix deadlock when AuthorizedKeysCommand or
AuthorizedPrincipalsCommand produces a lot of output and a key is
matched early.
- ssh(1): Fix typo in ~C error message for bad port forward
cancellation.
- ssh(1): Show a useful error message when included config files can't
be opened.
- sshd_config(5): Repair accidentally-deleted mention of %k token in
AuthorizedKeysCommand.
- sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM.
- ssh-agent(1): Relax PKCS#11 whitelist to include libexec and common
32-bit compatibility library directories.
- sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME
response handling.
- ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted keys.
It was not possible to delete them except by specifying their full
physical path.
- sshd(8): Avoid sandbox errors for Linux S390 systems using an ICA
crypto coprocessor.
- sshd(8): Fix non-exploitable weakness in seccomp-bpf sandbox arg
inspection.
- ssh-keygen(1), ssh(1), sftp(1): Fix output truncation for various that
contain non-printable characters where the codeset in use is ASCII.

openssh (1:7.4p1-1) unstable; urgency=medium
* New upstream release (http://www.openssh.com/txt/release-7.4):
- ssh(1): Remove 3des-cbc from the client's default proposal. 64-bit
block ciphers are not safe in 2016 and we don't want to wait until
attacks like SWEET32 are extended to SSH. As 3des-cbc was the only
mandatory cipher in the SSH RFCs, this may cause problems connecting
to older devices using the default configuration, but it's highly
likely that such devices already need explicit configuration for key
exchange and hostkey algorithms already anyway.
- sshd(8): When a forced-command appears in both a certificate and an
authorized keys/principals command= restriction, sshd will now refuse
to accept the certificate unless they are identical. The previous
(documented) behaviour of having the certificate forced-command
override the other could be a bit confusing and error-prone.
- sshd(8): Remove the UseLogin configuration directive and support for
having /bin/login manage login sessions.
- CVE-2016-10009: ssh-agent(1): Will now refuse to load PKCS#11 modules
from paths outside a trusted whitelist (run-time configurable).
Requests to load modules could be passed via agent forwarding and an
attacker could attempt to load a hostile PKCS#11 module across the
forwarded agent channel: PKCS#11 modules are shared libraries, so this
would result in code execution on the system running the ssh-agent if
the attacker has control of the forwarded agent-socket (on the host
running the sshd server) and the ability to write to the filesystem of
the host running ssh-agent (usually the host running the ssh client)
(closes: #848714).
- CVE-2016-10010: sshd(8): When privilege separation is disabled,
forwarded Unix-domain sockets would be created by sshd(8) with the
privileges of 'root' instead of the authenticated user. This release
refuses Unix-domain socket forwarding when privilege separation is
disabled (Privilege separation has been enabled by default for 14
years) (closes: #848715).
- CVE-2016-10011: sshd(8): Avoid theoretical leak of host private key
material to privilege-separated child processes via realloc() when
reading keys. No such leak was observed in practice for normal-sized
keys, nor does a leak to the child processes directly expose key
material to unprivileged users (closes: #848716).
- CVE-2016-10012: sshd(8): The shared memory manager used by
pre-authentication compression support had a bounds checks that could
be elided by some optimising compilers. Additionally, this memory
manager was incorrectly accessible when pre-authentication compression
was disabled. This could potentially allow attacks against the
privileged monitor process from the sandboxed privilege-separation
process (a compromise of the latter would be required first). This
release removes support for pre-authentication compression from
sshd(8) (closes: #848717).
- SECURITY: sshd(8): Validate address ranges for AllowUser and DenyUsers
directives at configuration load time and refuse to accept invalid
ones. It was previously possible to specify invalid CIDR address
ranges (e.g. user@127.1.2.3/55) and these would always match, possibly
resulting in granting access where it was not intended.
- ssh(1): Add a proxy multiplexing mode to ssh(1) inspired by the
version in PuTTY by Simon Tatham. This allows a multiplexing client
to communicate with the master process using a subset of the SSH
packet and channels protocol over a Unix-domain socket, with the main
process acting as a proxy that translates channel IDs, etc. This
allows multiplexing mode to run on systems that lack file-descriptor
passing (used by current multiplexing code) and potentially, in
conjunction with Unix-domain socket forwarding, with the client and
multiplexing master process on different machines. Multiplexing proxy
mode may be invoked using "ssh -O proxy ...".
- sshd(8): Add a sshd_config DisableForwarding option that disables X11,
agent, TCP, tunnel and Unix domain socket forwarding, as well as
anything else we might implement in the future. Like the 'restrict'
authorized_keys flag, this is intended to be a simple and future-proof
way of restricting an account.
- sshd(8), ssh(1): Support the "curve25519-sha256" key exchange method.
This is identical to the currently-supported method named
"curve25519-sha256@libssh.org".
- sshd(8): Improve handling of SIGHUP by checking to see if sshd is
already daemonised at startup and skipping the call to daemon(3) if it
is. This ensures that a SIGHUP restart of sshd(8) will retain the
same process-ID as the initial execution. sshd(8) will also now
unlink the PidFile prior to SIGHUP restart and re-create it after a
successful restart, rather than leaving a stale file in the case of a
configuration error.
- sshd(8): Allow ClientAliveInterval and ClientAliveCountMax directives
to appear in sshd_config Match blocks.
- sshd(8): Add %-escapes to AuthorizedPrincipalsCommand to match those
supported by AuthorizedKeysCommand (key, key type, fingerprint, etc.)
and a few more to provide access to the contents of the certificate
being offered.
- ssh(1): Allow IdentityFile to successfully load and use certificates
that have no corresponding bare public key.
- ssh(1): Fix public key authentication when multiple authentication is
in use and publickey is not just the first method attempted.
- ssh(1): Improve reporting when attempting to load keys from PKCS#11
tokens with fewer useless log messages and more detail in debug
messages.
- ssh(1): When tearing down ControlMaster connections, don't pollute
stderr when LogLevel=quiet.
- sftp(1): On ^Z wait for underlying ssh(1) to suspend before suspending
sftp(1) to ensure that ssh(1) restores the terminal mode correctly if
suspended during a password prompt.
- ssh(1): Avoid busy-wait when ssh(1) is suspended during a password
prompt (LP: #1646813).
- ssh(1), sshd(8): Correctly report errors during sending of ext-info
messages.
- sshd(8): Fix NULL-deref crash if sshd(8) received an out-of-sequence
NEWKEYS message.
- sshd(8): Correct list of supported signature algorithms sent in the
server-sig-algs extension.
- sshd(8): Fix sending ext_info message if privsep is disabled.
- sshd(8): More strictly enforce the expected ordering of privilege
separation monitor calls used for authentication and allow them only
when their respective authentication methods are enabled in the
configuration.
- sshd_config(5): Use 2001:db8::/32, the official IPv6 subnet for
configuration examples.
- On environments configured with Turkish locales, fall back to the
C/POSIX locale to avoid errors in configuration parsing caused by that
locale's unique handling of the letters 'i' and 'I' (LP: #1638338).
- contrib: Add a gnome-ssh-askpass3 with GTK+3 support.
- sshd(8): Improve PRNG reseeding across privilege separation and force
libcrypto to obtain a high-quality seed before chroot or sandboxing.
* Apply "wrap-and-sort -at -f debian/control -f debian/tests/control".
* Remove entries related to protocol 1 from the default sshd_config
generated on new installations.
* Remove some advice related to protocol 1 from README.Debian.
* Start handling /etc/ssh/sshd_config using ucf. The immediate motivation
for this is to deal with deprecations of options related to protocol 1,
but something like this has been needed for a long time (closes:
#419574, #848089):
- sshd_config is now a slightly-patched version of upstream's, and only
contains non-default settings (closes: #147201).
- I've included as many historical md5sums of default versions of
sshd_config as I could reconstruct from version control, but I'm sure
I've missed some.
- Explicitly synchronise the debconf database with the current
configuration file state in openssh-server.config, to ensure that the
PermitRootLogin setting is properly preserved.
- UsePrivilegeSeparation now defaults to the stronger "sandbox" rather
than "yes", per upstream.
* Remove redundant "GSSAPIDelegateCredentials no" from ssh_config (already
the upstream default), and document that setting ServerAliveInterval to
300 by default if BatchMode is set is Debian-specific (closes: #765630).
* Build gnome-ssh-askpass with GTK+ 3 (LP: #801187).

openssh (1:7.3p1-1) unstable; urgency=medium
* New upstream release (http://www.openssh.com/txt/release-7.3):
- SECURITY: sshd(8): Mitigate a potential denial-of-service attack
against the system's crypt(3) function via sshd(8). An attacker could
send very long passwords that would cause excessive CPU use in
crypt(3). sshd(8) now refuses to accept password authentication
requests of length greater than 1024 characters.
- SECURITY: ssh(1), sshd(8): Fix observable timing weakness in the CBC
padding oracle countermeasures. Note that CBC ciphers are disabled by
default and only included for legacy compatibility.
- SECURITY: ssh(1), sshd(8): Improve operation ordering of MAC
verification for Encrypt-then-MAC (EtM) mode transport MAC algorithms
to verify the MAC before decrypting any ciphertext. This removes the
possibility of timing differences leaking facts about the plaintext,
though no such leakage has been observed.
- ssh(1): Add a ProxyJump option and corresponding -J command-line flag
to allow simplified indirection through a one or more SSH bastions or
"jump hosts".
- ssh(1): Add an IdentityAgent option to allow specifying specific agent
sockets instead of accepting one from the environment.
- ssh(1): Allow ExitOnForwardFailure and ClearAllForwardings to be
optionally overridden when using ssh -W.
- ssh(1), sshd(8): Implement support for the IUTF8 terminal mode as per
draft-sgtatham-secsh-iutf8-00 (closes: #337041, LP: #394570).
- ssh(1), sshd(8): Add support for additional fixed Diffie-Hellman 2K,
4K and 8K groups from draft-ietf-curdle-ssh-kex-sha2-03.
- ssh-keygen(1), ssh(1), sshd(8): Support SHA256 and SHA512 RSA
signatures in certificates.
- ssh(1): Add an Include directive for ssh_config(5) files (closes:
#536031).
- ssh(1): Permit UTF-8 characters in pre-authentication banners sent
from the server.
- ssh(1), sshd(8): Reduce the syslog level of some relatively common
protocol events from LOG_CRIT.
- sshd(8): Refuse AuthenticationMethods="" in configurations and accept
AuthenticationMethods=any for the default behaviour of not requiring
multiple authentication.
- sshd(8): Remove obsolete and misleading "POSSIBLE BREAK-IN ATTEMPT!"
message when forward and reverse DNS don't match.
- ssh(1): Deduplicate LocalForward and RemoteForward entries to fix
failures when both ExitOnForwardFailure and hostname canonicalisation
are enabled.
- sshd(8): Remove fallback from moduli to obsolete "primes" file that
was deprecated in 2001 (LP: #1528251).
- sshd_config(5): Correct description of UseDNS: it affects ssh hostname
processing for authorized_keys, not known_hosts.
- sshd(8): Send ClientAliveInterval pings when a time-based RekeyLimit
is set; previously keepalive packets were not being sent.
- sshd(8): Whitelist more architectures to enable the seccomp-bpf
sandbox.
- scp(1): Respect the local user's LC_CTYPE locale (closes: #396295).
- Take character display widths into account for the progressmeter

openssh (1:7.2p1-1) unstable; urgency=medium
* New upstream release (http://www.openssh.com/txt/release-7.2):
- This release disables a number of legacy cryptographic algorithms by
default in ssh:
+ Several ciphers blowfish-cbc, cast128-cbc, all arcfour variants and
the rijndael-cbc aliases for AES.
+ MD5-based and truncated HMAC algorithms.
These algorithms are already disabled by default in sshd.
- ssh(1), sshd(8): Remove unfinished and unused roaming code (was
already forcibly disabled in OpenSSH 7.1p2).
- ssh(1): Eliminate fallback from untrusted X11 forwarding to trusted
forwarding when the X server disables the SECURITY extension.
- ssh(1), sshd(8): Increase the minimum modulus size supported for
diffie-hellman-group-exchange to 2048 bits.
- sshd(8): Pre-auth sandboxing is now enabled by default (previous
releases enabled it for new installations via sshd_config).
- all: Add support for RSA signatures using SHA-256/512 hash algorithms
based on draft-rsa-dsa-sha2-256-03.txt and draft-ssh-ext-info-04.txt.
- ssh(1): Add an AddKeysToAgent client option which can be set to 'yes',
'no', 'ask', or 'confirm', and defaults to 'no'. When enabled, a
private key that is used during authentication will be added to
ssh-agent if it is running (with confirmation enabled if set to
'confirm').
- sshd(8): Add a new authorized_keys option "restrict" that includes all
current and future key restrictions (no-*-forwarding, etc.). Also add
permissive versions of the existing restrictions, e.g. "no-pty" ->
"pty". This simplifies the task of setting up restricted keys and
ensures they are maximally-restricted, regardless of any permissions
we might implement in the future.
- ssh(1): Add ssh_config CertificateFile option to explicitly list
certificates.
- ssh-keygen(1): Allow ssh-keygen to change the key comment for all
supported formats (closes: #811125).
- ssh-keygen(1): Allow fingerprinting from standard input, e.g.
"ssh-keygen -lf -" (closes: #509058).
- ssh-keygen(1): Allow fingerprinting multiple public keys in a file,
e.g. "ssh-keygen -lf ~/.ssh/authorized_keys".
- sshd(8): Support "none" as an argument for sshd_config Foreground and
ChrootDirectory. Useful inside Match blocks to override a global
default.
- ssh-keygen(1): Support multiple certificates (one per line) and
reading from standard input (using "-f -") for "ssh-keygen -L"
- ssh-keyscan(1): Add "ssh-keyscan -c ..." flag to allow fetching
certificates instead of plain keys.
- ssh(1): Better handle anchored FQDNs (e.g. 'cvs.openbsd.org.') in
hostname canonicalisation - treat them as already canonical and remove
the trailing '.' before matching ssh_config.
- sftp(1): Existing destination directories should not terminate
recursive uploads (regression in OpenSSH 6.8; LP: #1553378).
* Use HTTPS for Vcs-* URLs, and link to cgit rather than gitweb.
* Restore slogin symlinks for compatibility, although they were removed
upstream.

* New upstream release (http://www.openssh.com/txt/release-7.1p2):
- CVE-2016-0777, CVE-2016-0778: Disable experimental client-side support
for roaming, which could be tricked by a malicious server into leaking
client memory to the server, including private client user keys; this
information leak is restricted to connections to malicious or
compromised servers (closes: #810984).
- SECURITY: Fix an out of-bound read access in the packet handling code.
Reported by Ben Hawkes.
- Further use of explicit_bzero has been added in various buffer
handling code paths to guard against compilers aggressively doing
dead-store removal.

openssh (1:7.1p1-1) unstable; urgency=medium
* New upstream release (http://www.openssh.com/txt/release-7.0, closes:
#785190):
- Support for the legacy SSH version 1 protocol is disabled by default
at compile time.
- Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is
disabled by default at run-time. It may be re-enabled using the
instructions at http://www.openssh.com/legacy.html
- Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by
default at run-time. These may be re-enabled using the instructions
at http://www.openssh.com/legacy.html
- Support for the legacy v00 cert format has been removed.
- The default for the sshd_config(5) PermitRootLogin option has changed
from "yes" to "prohibit-password".
- PermitRootLogin=without-password/prohibit-password now bans all
interactive authentication methods, allowing only public-key,
hostbased and GSSAPI authentication (previously it permitted
keyboard-interactive and password-less authentication if those were
enabled).
- ssh_config(5): Add PubkeyAcceptedKeyTypes option to control which
public key types are available for user authentication.
- sshd_config(5): Add HostKeyAlgorithms option to control which public
key types are offered for host authentications.
- ssh(1), sshd(8): Extend Ciphers, MACs, KexAlgorithms,
HostKeyAlgorithms, PubkeyAcceptedKeyTypes and HostbasedKeyTypes
options to allow appending to the default set of algorithms instead of
replacing it. Options may now be prefixed with a '+' to append to the
default, e.g. "HostKeyAlgorithms=+ssh-dss".
- sshd_config(5): PermitRootLogin now accepts an argument of
'prohibit-password' as a less-ambiguous synonym of 'without-
password'.
- ssh(1), sshd(8): Add compatability workarounds for Cisco and more
PuTTY versions.
- Fix some omissions and errors in the PROTOCOL and PROTOCOL.mux
documentation relating to Unix domain socket forwarding.
- ssh(1): Improve the ssh(1) manual page to include a better description
of Unix domain socket forwarding (closes: #779068).
- ssh(1), ssh-agent(1): Skip uninitialised PKCS#11 slots, fixing
failures to load keys when they are present.
- ssh(1), ssh-agent(1): Do not ignore PKCS#11 hosted keys that wth empty
CKA_ID.
- sshd(8): Clarify documentation for UseDNS option.
- Check realpath(3) behaviour matches what sftp-server requires and use
a replacement if necessary.
* New upstream release (http://www.openssh.com/txt/release-7.1):
- sshd(8): OpenSSH 7.0 contained a logic error in PermitRootLogin=
prohibit-password/without-password that could, depending on
compile-time configuration, permit password authentication to root
while preventing other forms of authentication. This problem was
reported by Mantas Mikulenas.
- ssh(1), sshd(8): Add compatibility workarounds for FuTTY.
- ssh(1), sshd(8): Refine compatibility workarounds for WinSCP.
- Fix a number of memory faults (double-free, free of uninitialised
memory, etc) in ssh(1) and ssh-keygen(1). Reported by Mateusz
Kocielski.
* Change "PermitRootLogin without-password" to the new preferred spelling
of "PermitRootLogin prohibit-password" in sshd_config, and update
documentation to reflect the new upstream default.
* Enable conch interoperability tests under autopkgtest.

openssh (1:6.9p1-1) unstable; urgency=medium
* New upstream release (http://www.openssh.com/txt/release-6.8):
- sshd(8): UseDNS now defaults to 'no'. Configurations that match
against the client host name (via sshd_config or authorized_keys) may
need to re-enable it or convert to matching against addresses.
- Add FingerprintHash option to ssh(1) and sshd(8), and equivalent
command-line flags to the other tools to control algorithm used for
key fingerprints. The default changes from MD5 to SHA256 and format
from hex to base64.
Fingerprints now have the hash algorithm prepended. An example of the
new format: SHA256:mVPwvezndPv/ARoIadVY98vAC0g+P/5633yTC4d/wXE
Please note that visual host keys will also be different.
- ssh(1), sshd(8): Experimental host key rotation support. Add a
protocol extension for a server to inform a client of all its
available host keys after authentication has completed. The client
may record the keys in known_hosts, allowing it to upgrade to better
host key algorithms and a server to gracefully rotate its keys.
The client side of this is controlled by a UpdateHostkeys config
option (default off).
- ssh(1): Add a ssh_config HostbasedKeyType option to control which host
public key types are tried during host-based authentication.
- ssh(1), sshd(8): Fix connection-killing host key mismatch errors when
sshd offers multiple ECDSA keys of different lengths.
- ssh(1): When host name canonicalisation is enabled, try to parse host
names as addresses before looking them up for canonicalisation. Fixes
bz#2074 and avoids needless DNS lookups in some cases.
- ssh(1), ssh-keysign(8): Make ed25519 keys work for host based
authentication.
- sshd(8): SSH protocol v.1 workaround for the Meyer, et al,
Bleichenbacher Side Channel Attack. Fake up a bignum key before RSA
decryption.
- sshd(8): Remember which public keys have been used for authentication
and refuse to accept previously-used keys. This allows
AuthenticationMethods=publickey,publickey to require that users
authenticate using two _different_ public keys.
- sshd(8): add sshd_config HostbasedAcceptedKeyTypes and
PubkeyAcceptedKeyTypes options to allow sshd to control what public
key types will be accepted (closes: #481133). Currently defaults to
all.
- sshd(8): Don't count partial authentication success as a failure
against MaxAuthTries.
- ssh(1): Add RevokedHostKeys option for the client to allow text-file
or KRL-based revocation of host keys.
- ssh-keygen(1), sshd(8): Permit KRLs that revoke certificates by serial
number or key ID without scoping to a particular CA.
- ssh(1): Add a "Match canonical" criteria that allows ssh_config Match
blocks to trigger only in the second config pass.
- ssh(1): Add a -G option to ssh that causes it to parse its
configuration and dump the result to stdout, similar to "sshd -T".
- ssh(1): Allow Match criteria to be negated. E.g. "Match !host".
- ssh-keyscan(1): ssh-keyscan has been made much more robust against
servers that hang or violate the SSH protocol (closes: #241119).
- ssh(1), ssh-keygen(1): Fix regression bz#2306: Key path names were
being lost as comment fields (closes: #787776).
- ssh(1): Allow ssh_config Port options set in the second config parse
phase to be applied (they were being ignored; closes: #774369).
- ssh(1): Tweak config re-parsing with host canonicalisation - make the
second pass through the config files always run when host name
canonicalisation is enabled (and not whenever the host name changes)
- ssh(1): Fix passing of wildcard forward bind addresses when connection
multiplexing is in use.
- ssh-keygen(1): Fix broken private key conversion from non-OpenSSH
formats.
- ssh-keygen(1): Fix KRL generation bug when multiple CAs are in use.
* New upstream release (http://www.openssh.com/txt/release-6.9):
- CVE-2015-5352: ssh(1): When forwarding X11 connections with
ForwardX11Trusted=no, connections made after ForwardX11Timeout expired
could be permitted and no longer subject to XSECURITY restrictions
because of an ineffective timeout check in ssh(1) coupled with "fail
open" behaviour in the X11 server when clients attempted connections
with expired credentials (closes: #790798). This problem was reported
by Jann Horn.
- SECURITY: ssh-agent(1): Fix weakness of agent locking (ssh-add -x) to
password guessing by implementing an increasing failure delay, storing
a salted hash of the password rather than the password itself and
using a timing-safe comparison function for verifying unlock attempts.
This problem was reported by Ryan Castellucci.
- sshd(8): Support admin-specified arguments to AuthorizedKeysCommand
(closes: #740494).
- sshd(8): Add AuthorizedPrincipalsCommand that allows retrieving
authorized principals information from a subprocess rather than a
file.
- ssh(1), ssh-add(1): Support PKCS#11 devices with external PIN entry
devices.
- ssh-keygen(1): Support "ssh-keygen -lF hostname" to search known_hosts
and print key hashes rather than full keys.
- ssh-agent(1): Add -D flag to leave ssh-agent in foreground without
enabling debug mode.
- ssh(1), sshd(8): Deprecate legacy SSH2_MSG_KEX_DH_GEX_REQUEST_OLD
message and do not try to use it against some 3rd-party SSH
implementations that use it (older PuTTY, WinSCP).
- ssh(1), sshd(8): Cap DH-GEX group size at 4Kbits for Cisco
implementations as some would fail when attempting to use group sizes
>4K (closes: #740307, LP: #1287222).
- ssh(1): Fix out-of-bound read in EscapeChar configuration option
parsing.
- sshd(8): Fix application of PermitTunnel, LoginGraceTime,
AuthenticationMethods and StreamLocalBindMask options in Match blocks.
- ssh(1), sshd(8): Improve disconnection message on TCP reset.
- ssh(1): Remove failed remote forwards established by multiplexing from
the list of active forwards.
- sshd(8): Make parsing of authorized_keys "environment=" options
independent of PermitUserEnv being enabled.
- sshd(8): Fix post-auth crash with permitopen=none (closes: #778807).
- ssh(1), ssh-add(1), ssh-keygen(1): Allow new-format private keys to be
encrypted with AEAD ciphers.
- ssh(1): Allow ListenAddress, Port and AddressFamily configuration
options to appear in any order.
- sshd(8): Check for and reject missing arguments for VersionAddendum
and ForceCommand.
- ssh(1), sshd(8): Don't treat unknown certificate extensions as fatal.
- ssh-keygen(1): Make stdout and stderr output consistent.
- ssh(1): Mention missing DISPLAY environment in debug log when X11
forwarding requested.
- sshd(8): Correctly record login when UseLogin is set.
- sshd(8): Add some missing options to sshd -T output and fix output of
VersionAddendum and HostCertificate.
- Document and improve consistency of options that accept a "none"
argument: TrustedUserCAKeys, RevokedKeys, AuthorizedPrincipalsFile.
- ssh(1): Include remote username in debug output.
- sshd(8): Avoid compatibility problem with some versions of Tera Term,
which would crash when they received the hostkeys notification message
(hostkeys-00@openssh.com).
- sshd(8): Mention ssh-keygen -E as useful when comparing legacy MD5
host key fingerprints.
- ssh(1): Clarify pseudo-terminal request behaviour and make manual
language consistent.
- ssh(1): Document that the TERM environment variable is not subject to
SendEnv and AcceptEnv; bz#2386
- sshd(8): Format UsePAM setting when using sshd -T (closes: #767648).
- moduli(5): Update DH-GEX moduli (closes: #787037).
* There are some things I want to fix before upgrading to 7.0p1, though I
intend to do that soon. In the meantime, backport some patches, mainly
to fix security issues:
- SECURITY: sshd(8): OpenSSH 6.8 and 6.9 incorrectly set TTYs to be
world-writable. Local attackers may be able to write arbitrary
messages to logged-in users, including terminal escape sequences.
Reported by Nikolay Edigaryev.
- SECURITY: sshd(8): Fixed a privilege separation weakness related to
PAM support. Attackers who could successfully compromise the
pre-authentication process for remote code execution and who had valid
credentials on the host could impersonate other users. Reported by
Moritz Jodeit.
- SECURITY: sshd(8): Fixed a use-after-free bug related to PAM support
that was reachable by attackers who could compromise the
pre-authentication process for remote code execution (closes:
#795711). Also reported by Moritz Jodeit.
- CVE-2015-5600: sshd(8): Fix circumvention of MaxAuthTries using
keyboard-interactive authentication (closes: #793616). By specifying
a long, repeating keyboard-interactive "devices" string, an attacker
could request the same authentication method be tried thousands of
times in a single pass. The LoginGraceTime timeout in sshd(8) and any
authentication failure delays implemented by the authentication
mechanism itself were still applied. Found by Kingcope.
- Let principals-command.sh work for noexec /var/run.

openssh (1:6.7p1-1) unstable; urgency=medium
* New upstream release (http://www.openssh.com/txt/release-6.7):
- sshd(8): The default set of ciphers and MACs has been altered to
remove unsafe algorithms. In particular, CBC ciphers and arcfour* are
disabled by default. The full set of algorithms remains available if
configured explicitly via the Ciphers and MACs sshd_config options.
- ssh(1), sshd(8): Add support for Unix domain socket forwarding. A
remote TCP port may be forwarded to a local Unix domain socket and
vice versa or both ends may be a Unix domain socket (closes: #236718).
- ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for ED25519
key types.
- sftp(1): Allow resumption of interrupted uploads.
- ssh(1): When rekeying, skip file/DNS lookups of the hostkey if it is
the same as the one sent during initial key exchange.
- sshd(8): Allow explicit ::1 and 127.0.0.1 forwarding bind addresses
when GatewayPorts=no; allows client to choose address family.
- sshd(8): Add a sshd_config PermitUserRC option to control whether
~/.ssh/rc is executed, mirroring the no-user-rc authorized_keys
option.
- ssh(1): Add a %C escape sequence for LocalCommand and ControlPath that
expands to a unique identifier based on a hash of the tuple of (local
host, remote user, hostname, port). Helps avoid exceeding miserly
pathname limits for Unix domain sockets in multiplexing control paths.
- sshd(8): Make the "Too many authentication failures" message include
the user, source address, port and protocol in a format similar to the
authentication success / failure messages.
- Use CLOCK_BOOTTIME in preference to CLOCK_MONOTONIC when it is
available. It considers time spent suspended, thereby ensuring
timeouts (e.g. for expiring agent keys) fire correctly (closes:
#734553).
- Use prctl() to prevent sftp-server from accessing
/proc/self/{mem,maps}.
* Restore TCP wrappers support, removed upstream in 6.7. It is true that
dropping this reduces preauth attack surface in sshd. On the other
hand, this support seems to be quite widely used, and abruptly dropping
it (from the perspective of users who don't read openssh-unix-dev) could
easily cause more serious problems in practice. It's not entirely clear
what the right long-term answer for Debian is, but it at least probably
doesn't involve dropping this feature shortly before a freeze.
* Replace patch to disable OpenSSL version check with an updated version
of Kurt Roeckx's patch from #732940 to just avoid checking the status
field.
* Build-depend on a new enough dpkg-dev for dpkg-buildflags, rather than
simply a new enough dpkg.
* Simplify debian/rules using /usr/share/dpkg/buildflags.mk.

* Run a subset of the upstream regression test suite at package build

* Remove tests for whether /dev/null is a character device from the
Upstart job and the systemd service files; it's there to avoid a
confusing failure mode in daemon(), but with modern init systems we use
the -D option to suppress daemonisation anyway.

* New upstream release (http://www.openssh.com/txt/release-6.5,

- ssh(1): Add support for client-side hostname canonicalisation using a
set of DNS suffixes and rules in ssh_config(5). This allows
unqualified names to be canonicalised to fully-qualified domain names
to eliminate ambiguity when looking up keys in known_hosts or checking
host certificate names (closes: #115286).
* Switch to git; adjust Vcs-* fields.
* Convert to git-dpm, and drop source package documentation associated
with the old bzr/quilt patch handling workflow.
* Drop ssh-vulnkey and the associated ssh/ssh-add/sshd integration code,
leaving only basic configuration file compatibility, since it has been
nearly six years since the original vulnerability and this code is not
likely to be of much value any more (closes: #481853, #570651). See
https://lists.debian.org/debian-devel/2013/09/msg00240.html for my full

* Add the pam_keyinit session module, to create a new session keyring on

* Incorporate default path changes from shadow 1:4.0.18.1-8, removing
/usr/bin/X11 (closes: #644521).
* Generate ED25519 host keys on fresh installations. Upgraders who wish
to add such host keys should manually add 'HostKey

* If the running init daemon is Upstart, then, on the first upgrade to

openssh (1:6.2p2-2) unstable; urgency=low
* Change start condition of Upstart job to be just the standard "runlevel
[2345]", rather than "filesystem or runlevel [2345]"; the latter makes
it unreasonably difficult to ensure that urandom starts before ssh, and
is not really necessary since one of static-network-up and failsafe-boot
is guaranteed to happen and will trigger entry to the default runlevel,
and we don't care about ssh starting before the network (LP: #1098299).
* Drop conffile handling for direct upgrades from pre-split ssh package;
this was originally added in 1:4.3p2-7 / 1:4.3p2-8, and contained a
truly ghastly hack around a misbehaviour in sarge's dpkg. Since this is
now four Debian releases ago, we can afford to drop this and simplify
the packaging.
* Remove ssh/use_old_init_script, which was a workaround for a very old
bug in /etc/init.d/ssh. If anyone has ignored this for >10 years then
they aren't going to be convinced now (closes: #214182).
* Remove support for upgrading directly from ssh-nonfree.
* Remove lots of maintainer script support for direct upgrades from
pre-etch (three releases before current stable).
* Add #DEBHELPER# tokens to openssh-client.postinst and
openssh-server.postinst.
* Replace old manual conffile handling code with dpkg-maintscript-helper,
via dh_installdeb.
* Switch to new unified layout for Upstart jobs as documented in
https://wiki.ubuntu.com/UpstartCompatibleInitScripts: the init script
checks for a running Upstart, and we now let dh_installinit handle most
of the heavy lifting in maintainer scripts. Ubuntu users should be
essentially unaffected except that sshd may no longer start
automatically in chroots if the running Upstart predates 0.9.0; but the
main goal is simply not to break when openssh-server is installed in a
chroot.
* Remove the check for vulnerable host keys; this was first added five
years ago, and everyone should have upgraded through a version that
applied these checks by now. The ssh-vulnkey tool and the blacklisting
support in sshd are still here, at least for the moment.
* This removes the last of our uses of debconf (closes: #221531).

openssh (1:5.7p1-1) experimental; urgency=low
* New upstream release (http://www.openssh.com/txt/release-5.7):
- Implement Elliptic Curve Cryptography modes for key exchange (ECDH)
and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA
offer better performance than plain DH and DSA at the same equivalent
symmetric key length, as well as much shorter keys.
- sftp(1)/sftp-server(8): add a protocol extension to support a hard
link operation. It is available through the "ln" command in the
client. The old "ln" behaviour of creating a symlink is available
using its "-s" option or through the preexisting "symlink" command.
- scp(1): Add a new -3 option to scp: Copies between two remote hosts
are transferred through the local host (closes: #508613).
- ssh(1): "atomically" create the listening mux socket by binding it on
a temporary name and then linking it into position after listen() has
succeeded. This allows the mux clients to determine that the server
socket is either ready or stale without races (closes: #454784).
Stale server sockets are now automatically removed (closes: #523250).
- ssh(1): install a SIGCHLD handler to reap expired child process
(closes: #594687).
- ssh(1)/ssh-agent(1): honour $TMPDIR for client xauth and ssh-agent
temporary directories (closes: #357469, although only if you arrange
for ssh-agent to actually see $TMPDIR since the setgid bit will cause
it to be stripped off).
* Update to current GSSAPI patch from
http://www.sxw.org.uk/computing/patches/openssh-5.7p1-gsskex-all-20110125.patch:
- Add GSSAPIServerIdentity option.
* Generate ECDSA host keys on fresh installations. Upgraders who wish to
add such host keys should manually add 'HostKey
/etc/ssh/ssh_host_ecdsa_key' to /etc/ssh/sshd_config and run 'ssh-keygen
-q -f /etc/ssh/ssh_host_ecdsa_key -N "" -t ecdsa'.
* Build-depend on libssl-dev (>= 0.9.8g) to ensure sufficient ECC support.
* Backport SELinux build fix from CVS.
* Rearrange selinux-role.patch so that it links properly given this
SELinux build fix.

openssh (1:5.4p1-1) unstable; urgency=low
* New upstream release (LP: #535029).
- After a transition period of about 10 years, this release disables SSH
protocol 1 by default. Clients and servers that need to use the
legacy protocol must explicitly enable it in ssh_config / sshd_config
or on the command-line.
- Remove the libsectok/OpenSC-based smartcard code and add support for
PKCS#11 tokens. This support is enabled by default in the Debian
packaging, since it now doesn't involve additional library
dependencies (closes: #231472, LP: #16918).
- Add support for certificate authentication of users and hosts using a
new, minimal OpenSSH certificate format (closes: #482806).
- Added a 'netcat mode' to ssh(1): "ssh -W host:port ...".
- Add the ability to revoke keys in sshd(8) and ssh(1). (For the Debian
package, this overlaps with the key blacklisting facility added in
openssh 1:4.7p1-9, but with different file formats and slightly
different scopes; for the moment, I've roughly merged the two.)
- Various multiplexing improvements, including support for requesting
port-forwardings via the multiplex protocol (closes: #360151).
- Allow setting an explicit umask on the sftp-server(8) commandline to
override whatever default the user has (closes: #496843).
- Many sftp client improvements, including tab-completion, more options,
and recursive transfer support for get/put (LP: #33378). The old
mget/mput commands never worked properly and have been removed
(closes: #270399, #428082).
- Do not prompt for a passphrase if we fail to open a keyfile, and log
the reason why the open failed to debug (closes: #431538).
- Prevent sftp from crashing when given a "-" without a command. Also,
allow whitespace to follow a "-" (closes: #531561).
* Fix 'debian/rules quilt-setup' to avoid writing .orig files if some
patches apply with offsets.
* Include debian/ssh-askpass-gnome.png in the Debian tarball now that
we're using a source format that permits this, rather than messing
around with uudecode.
* Drop compatibility with the old gssapi mechanism used in ssh-krb5 <<
3.8.1p1-1. Simon Wilkinson refused this patch since the old gssapi
mechanism was removed due to a serious security hole, and since these
versions of ssh-krb5 are no longer security-supported by Debian I don't
think there's any point keeping client compatibility for them.
* Fix substitution of ETC_PAM_D_SSH, following the rename in 1:4.7p1-4.
* Hardcode the location of xauth to /usr/bin/xauth rather than
/usr/bin/X11/xauth (thanks, Aron Griffis; closes: #575725, LP: #8440).
xauth no longer depends on x11-common, so we're no longer guaranteed to
have the /usr/bin/X11 symlink available. I was taking advantage of the
/usr/bin/X11 symlink to smooth X's move to /usr/bin, but this is far
enough in the past now that it's probably safe to just use /usr/bin.
* Remove SSHD_OOM_ADJUST configuration. sshd now unconditionally makes
itself non-OOM-killable, and doesn't require configuration to avoid log
spam in virtualisation containers (closes: #555625).
* Drop Debian-specific removal of OpenSSL version check. Upstream ignores
the two patchlevel nybbles now, which is sufficient to address the
original reason this change was introduced, and it appears that any
change in the major/minor/fix nybbles would involve a new libssl package
name. (We'd still lose if the status nybble were ever changed, but that
would mean somebody had packaged a development/beta version rather than
a proper release, which doesn't appear to be normal practice.)
* Drop most of our "LogLevel SILENT" (-qq) patch. This was originally
introduced to match the behaviour of non-free SSH, in which -q does not
suppress fatal errors, but matching the behaviour of OpenSSH upstream is
much more important nowadays. We no longer document that -q does not
suppress fatal errors (closes: #280609). Migrate "LogLevel SILENT" to
"LogLevel QUIET" in sshd_config on upgrade.
* Policy version 3.8.4:
- Add a Homepage field.

* Backport from upstream:
- After sshd receives a SIGHUP, ignore subsequent HUPs while sshd

- Output a debug if we can't open an existing keyfile (LP: #505301).
* Use host compiler for ssh-askpass-gnome when cross-compiling.
* Don't run tests when cross-compiling.
* Drop change from 1:3.6.1p2-5 to disable cmsg_type check for file
descriptor passing when running on Linux 2.0. The previous stable
release of Debian dropped support for Linux 2.4, let alone 2.0, so this
very likely has no remaining users depending on it.

- Change the default cipher order to prefer the AES CTR modes and the
revised "arcfour256" mode to CBC mode ciphers that are susceptible to
CPNI-957037 "Plaintext Recovery Attack Against SSH".
- Add countermeasures to mitigate CPNI-957037-style attacks against the
SSH protocol's use of CBC-mode ciphers. Upon detection of an invalid
packet length or Message Authentication Code, ssh/sshd will continue
reading up to the maximum supported packet length rather than
immediately terminating the connection. This eliminates most of the
known differences in behaviour that leaked information about the
plaintext of injected data which formed the basis of this attack
(closes: #506115, LP: #379329).
- ForceCommand directive now accepts commandline arguments for the
internal-sftp server (closes: #524423, LP: #362511).
- Add AllowAgentForwarding to available Match keywords list (closes:

- Make ssh(1) send the correct channel number for
SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE messages to
avoid triggering 'Non-public channel' error messages on sshd(8) in
openssh-5.1.
- Avoid printing 'Non-public channel' warnings in sshd(8), since the
ssh(1) has sent incorrect channel numbers since ~2004 (this reverts a
behaviour introduced in openssh-5.1; closes: #496017).
- Disable nonfunctional ssh(1) ~C escape handler in multiplex slave

openssh (1:5.1p1-1) unstable; urgency=low
* New upstream release (closes: #474301). Important changes not previously
backported to 4.7p1:
- 4.9/4.9p1 (http://www.openssh.com/txt/release-4.9):
+ Added chroot(2) support for sshd(8), controlled by a new option
"ChrootDirectory" (closes: #139047, LP: #24777).
+ Linked sftp-server(8) into sshd(8). The internal sftp server is used
when the command "internal-sftp" is specified in a Subsystem or
ForceCommand declaration. When used with ChrootDirectory, the
internal sftp server requires no special configuration of files
inside the chroot environment.
+ Added a protocol extension method "posix-rename@openssh.com" for
sftp-server(8) to perform POSIX atomic rename() operations; sftp(1)
prefers this if available (closes: #308561).
+ Removed the fixed limit of 100 file handles in sftp-server(8).
+ ssh(8) will now skip generation of SSH protocol 1 ephemeral server
keys when in inetd mode and protocol 2 connections are negotiated.
This speeds up protocol 2 connections to inetd-mode servers that
also allow Protocol 1.
+ Accept the PermitRootLogin directive in a sshd_config(5) Match
block. Allows for, e.g. permitting root only from the local network.
+ Reworked sftp(1) argument splitting and escaping to be more
internally consistent (i.e. between sftp commands) and more
consistent with sh(1). Please note that this will change the
interpretation of some quoted strings, especially those with
embedded backslash escape sequences.
+ Support "Banner=none" in sshd_config(5) to disable sending of a
pre-login banner (e.g. in a Match block).
+ ssh(1) ProxyCommands are now executed with $SHELL rather than
/bin/sh.
+ ssh(1)'s ConnectTimeout option is now applied to both the TCP
connection and the SSH banner exchange (previously it just covered
the TCP connection). This allows callers of ssh(1) to better detect
and deal with stuck servers that accept a TCP connection but don't
progress the protocol, and also makes ConnectTimeout useful for
connections via a ProxyCommand.
+ scp(1) incorrectly reported "stalled" on slow copies (closes:
#140828).
+ scp(1) date underflow for timestamps before epoch.
+ ssh(1) used the obsolete SIG DNS RRtype for host keys in DNS,
instead of the current standard RRSIG.
+ Correctly drain ACKs when a sftp(1) upload write fails midway,
avoids a fatal() exit from what should be a recoverable condition.
+ Fixed ssh-keygen(1) selective host key hashing (i.e. "ssh-keygen -HF
hostname") to not include any IP address in the data to be hashed.
+ Make ssh(1) skip listening on the IPv6 wildcard address when a
binding address of 0.0.0.0 is used against an old SSH server that
does not support the RFC4254 syntax for wildcard bind addresses.
+ Enable IPV6_V6ONLY socket option on sshd(8) listen socket, as is
already done for X11/TCP forwarding sockets (closes: #439661).
+ Fix FD leak that could hang a ssh(1) connection multiplexing master.
+ Make ssh(1) -q option documentation consistent with reality.
+ Fixed sshd(8) PAM support not calling pam_session_close(), or
failing to call it with root privileges (closes: #372680).
+ Fix activation of OpenSSL engine support when requested in configure
(LP: #119295).
+ Cache SELinux status earlier so we know if it's enabled after a
chroot (LP: #237557).
- 5.1/5.1p1 (http://www.openssh.com/txt/release-5.1):
+ Introduce experimental SSH Fingerprint ASCII Visualisation to ssh(1)
and ssh-keygen(1). Visual fingerprint display is controlled by a new
ssh_config(5) option "VisualHostKey". The intent is to render SSH
host keys in a visual form that is amenable to easy recall and
rejection of changed host keys.
+ sshd_config(5) now supports CIDR address/masklen matching in "Match
address" blocks, with a fallback to classic wildcard matching.
+ sshd(8) now supports CIDR matching in ~/.ssh/authorized_keys
from="..." restrictions, also with a fallback to classic wildcard
matching.
+ Added an extended test mode (-T) to sshd(8) to request that it write
its effective configuration to stdout and exit. Extended test mode
also supports the specification of connection parameters (username,
source address and hostname) to test the application of
sshd_config(5) Match rules.
+ ssh(1) now prints the number of bytes transferred and the overall
connection throughput for SSH protocol 2 sessions when in verbose
mode (previously these statistics were displayed for protocol 1
connections only).
+ sftp-server(8) now supports extension methods statvfs@openssh.com
and fstatvfs@openssh.com that implement statvfs(2)-like operations.
+ sftp(1) now has a "df" command to the sftp client that uses the
statvfs@openssh.com to produce a df(1)-like display of filesystem
space and inode utilisation (requires statvfs@openssh.com support on
the server).
+ Added a MaxSessions option to sshd_config(5) to allow control of the
number of multiplexed sessions supported over a single TCP
connection. This allows increasing the number of allowed sessions
above the previous default of 10, disabling connection multiplexing
(MaxSessions=1) or disallowing login/shell/subsystem sessions
entirely (MaxSessions=0).
+ Added a no-more-sessions@openssh.com global request extension that
is sent from ssh(1) to sshd(8) when the client knows that it will
never request another session (i.e. when session multiplexing is
disabled). This allows a server to disallow further session requests
and terminate the session in cases where the client has been
hijacked.
+ ssh-keygen(1) now supports the use of the -l option in combination
with -F to search for a host in ~/.ssh/known_hosts and display its
fingerprint.
+ ssh-keyscan(1) now defaults to "rsa" (protocol 2) keys, instead of
"rsa1" (LP: #129794).
+ Added an AllowAgentForwarding option to sshd_config(8) to control
whether authentication agent forwarding is permitted. Note that this
is a loose control, as a client may install their own unofficial
forwarder.
+ ssh(1) and sshd(8): avoid unnecessary malloc/copy/free when
receiving network data, resulting in a ~10% speedup.
+ ssh(1) and sshd(8) will now try additional addresses when connecting
to a port forward destination whose DNS name resolves to more than
one address. The previous behaviour was to try the only first
address and give up if that failed.
+ ssh(1) and sshd(8) now support signalling that channels are
half-closed for writing, through a channel protocol extension
notification "eow@openssh.com". This allows propagation of closed
file descriptors, so that commands such as "ssh -2 localhost od
/bin/ls | true" do not send unnecessary data over the wire.
+ sshd(8): increased the default size of ssh protocol 1 ephemeral keys
from 768 to 1024 bits.
+ When ssh(1) has been requested to fork after authentication ("ssh
-f") with ExitOnForwardFailure enabled, delay the fork until after
replies for any -R forwards have been seen. Allows for robust
detection of -R forward failure when using -f.
+ "Match group" blocks in sshd_config(5) now support negation of
groups. E.g. "Match group staff,!guests".
+ sftp(1) and sftp-server(8) now allow chmod-like operations to set
set[ug]id/sticky bits.
+ The MaxAuthTries option is now permitted in sshd_config(5) match
blocks.
+ Multiplexed ssh(1) sessions now support a subset of the ~ escapes
that are available to a primary connection.
+ ssh(1) connection multiplexing will now fall back to creating a new
connection in most error cases (closes: #352830).
+ Make ssh(1) deal more gracefully with channel requests that fail.
Previously it would optimistically assume that requests would always
succeed, which could cause hangs if they did not (e.g. when the
server runs out of file descriptors).
+ ssh(1) now reports multiplexing errors via the multiplex slave's
stderr where possible (subject to LogLevel in the mux master).
+ Fixed an UMAC alignment problem that manifested on Itanium
platforms.

* New upstream release (closes: #453367).
- CVE-2007-4752: Prevent ssh(1) from using a trusted X11 cookie if
creation of an untrusted cookie fails; found and fixed by Jan Pechanec
(closes: #444738).
- sshd(8) in new installations defaults to SSH Protocol 2 only. Existing
installations are unchanged.
- The SSH channel window size has been increased, and both ssh(1)
sshd(8) now send window updates more aggressively. These improves
performance on high-BDP (Bandwidth Delay Product) networks.
- ssh(1) and sshd(8) now preserve MAC contexts between packets, which
saves 2 hash calls per packet and results in 12-16% speedup for
arcfour256/hmac-md5.
- A new MAC algorithm has been added, UMAC-64 (RFC4418) as
"umac-64@openssh.com". UMAC-64 has been measured to be approximately
20% faster than HMAC-MD5.
- Failure to establish a ssh(1) TunnelForward is now treated as a fatal
error when the ExitOnForwardFailure option is set.
- ssh(1) returns a sensible exit status if the control master goes away
without passing the full exit status.
- When using a ProxyCommand in ssh(1), set the outgoing hostname with
gethostname(2), allowing hostbased authentication to work.
- Make scp(1) skip FIFOs rather than hanging (closes: #246774).
- Encode non-printing characters in scp(1) filenames. These could cause
copies to be aborted with a "protocol error".
- Handle SIGINT in sshd(8) privilege separation child process to ensure
that wtmp and lastlog records are correctly updated.
- Report GSSAPI mechanism in errors, for libraries that support multiple
mechanisms.
- Improve documentation for ssh-add(1)'s -d option.
- Rearrange and tidy GSSAPI code, removing server-only code being linked
into the client.
- Delay execution of ssh(1)'s LocalCommand until after all forwardings
have been established.
- In scp(1), do not truncate non-regular files.
- Improve exit message from ControlMaster clients.
- Prevent sftp-server(8) from reading until it runs out of buffer space,

openssh (1:4.6p1-1) unstable; urgency=low
* New upstream release (closes: #395507, #397961, #420035). Important
changes not previously backported to 4.3p2:
- 4.4/4.4p1 (http://www.openssh.com/txt/release-4.4):
+ On portable OpenSSH, fix a GSSAPI authentication abort that could be
used to determine the validity of usernames on some platforms.
+ Implemented conditional configuration in sshd_config(5) using the
"Match" directive. This allows some configuration options to be
selectively overridden if specific criteria (based on user, group,
hostname and/or address) are met. So far a useful subset of
post-authentication options are supported and more are expected to
be added in future releases.
+ Add support for Diffie-Hellman group exchange key agreement with a
final hash of SHA256.
+ Added a "ForceCommand" directive to sshd_config(5). Similar to the
command="..." option accepted in ~/.ssh/authorized_keys, this forces
the execution of the specified command regardless of what the user
requested. This is very useful in conjunction with the new "Match"
option.
+ Add a "PermitOpen" directive to sshd_config(5). This mirrors the
permitopen="..." authorized_keys option, allowing fine-grained
control over the port-forwardings that a user is allowed to
establish.
+ Add optional logging of transactions to sftp-server(8).
+ ssh(1) will now record port numbers for hosts stored in
~/.ssh/known_hosts when a non-standard port has been requested
(closes: #50612).
+ Add an "ExitOnForwardFailure" option to cause ssh(1) to exit (with a
non-zero exit code) when requested port forwardings could not be
established.
+ Extend sshd_config(5) "SubSystem" declarations to allow the
specification of command-line arguments.
+ Replacement of all integer overflow susceptible invocations of
malloc(3) and realloc(3) with overflow-checking equivalents.
+ Many manpage fixes and improvements.
+ Add optional support for OpenSSL hardware accelerators (engines),
enabled using the --with-ssl-engine configure option.
+ Tokens in configuration files may be double-quoted in order to
contain spaces (closes: #319639).

* New upstream release (closes: #361032).
- CVE-2006-0225: scp (as does rcp, on which it is based) invoked a
subshell to perform local to local, and remote to remote copy
operations. This subshell exposed filenames to shell expansion twice;
allowing a local attacker to create filenames containing shell
metacharacters that, if matched by a wildcard, could lead to execution
of attacker-specified commands with the privilege of the user running
scp (closes: #349645).
- Add support for tunneling arbitrary network packets over a connection
between an OpenSSH client and server via tun(4) virtual network
interfaces. This allows the use of OpenSSH (4.3+) to create a true VPN
between the client and server providing real network connectivity at
layer 2 or 3. This feature is experimental.
- Reduce default key length for new DSA keys generated by ssh-keygen
back to 1024 bits. DSA is not specified for longer lengths and does
not fully benefit from simply making keys longer. As per FIPS 186-2
Change Notice 1, ssh-keygen will refuse to generate a new DSA key
smaller or larger than 1024 bits.
- Fixed X forwarding failing to start when the X11 client is executed in
background at the time of session exit.
- Change ssh-keygen to generate a protocol 2 RSA key when invoked
without arguments (closes: #114894).
- Fix timing variance for valid vs. invalid accounts when attempting
Kerberos authentication.
- Ensure that ssh always returns code 255 on internal error
(closes: #259865).
- Cleanup wtmp files on SIGTERM when not using privsep.
- Set SO_REUSEADDR on X11 listeners to avoid problems caused by
lingering sockets from previous session (X11 applications can
sometimes not connect to 127.0.0.1:60xx) (closes:
https://launchpad.net/bugs/25528).
- Ensure that fds 0, 1 and 2 are always attached in all programs, by
duping /dev/null to them if necessary.
- Xauth list invocation had bogus "." argument.
- Remove internal assumptions on key exchange hash algorithm and output
length, preparing OpenSSH for KEX methods with alternate hashes.
- Ignore junk sent by a server before it sends the "SSH-" banner.
- Many manual page improvements.
- Lots of cleanups, including fixes to memory leaks on error paths and
possible crashes.

(closes: #326065).
- SECURITY (CAN-2005-2798): Fix improper delegation of GSSAPI
credentials. This code is only built in openssh-krb5, not openssh, but
I mention the CVE reference here anyway for completeness.
- Add a new compression method ("Compression delayed") that delays zlib
compression until after authentication, eliminating the risk of zlib
vulnerabilities being exploited by unauthenticated users. Note that
users of OpenSSH versions earlier than 3.5 will need to disable
compression on the client or set "Compression yes" (losing this
security benefit) on the server.
- Increase the default size of new RSA/DSA keys generated by ssh-keygen
from 1024 to 2048 bits (closes: #181162).
- Many bugfixes and improvements to connection multiplexing.
- Don't pretend to accept $HOME (closes: #208648).
* debian/rules: Resynchronise CFLAGS with that generated by configure.
* openssh-client and openssh-server conflict with pre-split ssh to avoid

* Set X11Forwarding to yes in the default sshd_config (new installs only).
At least when X11UseLocalhost is turned on, which is the default, the

openssh (1:4.0p1-1) experimental; urgency=low
* New upstream release.
- Port-forwarding specifications now take optional bind addresses, and
the server allows client-specified bind addresses for remote port
forwardings when configured with "GatewayPorts clientspecified"
(closes: #87253, #192206).
- ssh and ssh-keyscan now support hashing of known_hosts files for
improved privacy (CAN-2005-2666). ssh-keygen has new options for
managing known_hosts files, which understand hashing.
- sftp supports command history and editing support using libedit
(closes: #287013).
- Have scp and sftp wait for the spawned ssh to exit before they exit
themselves, allowing ssh to restore terminal modes (closes: #257130).
- Improved the handling of bad data in authorized_keys files,
eliminating fatal errors on corrupt or very large keys; e.g. linefeeds
in keys only produce errors in auth.log now (closes: #220726).
- Add "command mode" to ssh connection multiplexing (closes: #303452).
- Mention $HOME/.hushlogin in sshd(8) FILES section (closes: #163933).
* Make gnome-ssh-askpass stay above other windows (thanks, Liyang HU;
closes: #296487).
* Remove obsolete and unnecessary ssh/forward_warning debconf note.
* Hurd build fixes (although sshd still doesn't work):
- Restore X forwarding fix from #102991, lost somewhere along the way.
- Link with -lcrypt.
- Link with -lpthread rather than -pthread.
- Don't build ssh-askpass-gnome on the Hurd, until GNOME is available to
satisfy build-dependencies.
* Drop workaround for #242462 on amd64; it's been fixed properly upstream.
* Enable HashKnownHosts by default. This only affects new entries; use
'ssh-keygen -H' to convert an entire known_hosts file to hashed format.
* Note in ssh_config(5) that the SetupTimeOut option is Debian-specific
(closes: #307069).
* debconf template translations:
- Update Czech (thanks, Miroslav Kure; closes: #298744).
- Update Finnish (thanks, Matti Pöllä; closes: #303787).

openssh (1:3.8.1p1-9) experimental; urgency=low
* Split the ssh binary package into openssh-client and openssh-server
(closes: #39741). openssh-server depends on openssh-client for some
common functionality; it didn't seem worth creating yet another package
for this. openssh-client is priority standard, openssh-server optional.
* New transitional ssh package, priority optional, depending on
openssh-client and openssh-server. May be removed once nothing depends
on it.
* When upgrading from ssh to openssh-{client,server}, it's very difficult
for the maintainer scripts to find out what version we're upgrading from
without dodgy dpkg hackery. I've therefore taken the opportunity to move
a couple of debconf notes into NEWS files, namely ssh/ssh2_keys_merged
and ssh/user_environment_tell.
* Add a heuristic to try to make sure the sshd_config upgrade to >= 3.7
happens even though we don't know what version we're upgrading from.
* Remove /etc/ssh/sshd_not_to_be_run on purge of openssh-server. For now
(until sarge+2) it's still honoured to avoid breaking existing
configurations, but the right approach is now to remove the
openssh-server package if you don't want to run the server. Add a NEWS
item to that effect.

openssh (1:3.8p1-1) unstable; urgency=low
* New upstream release (closes: #232281):
- New PAM implementation based on that in FreeBSD. This runs PAM session
modules before dropping privileges (closes: #132681, #150968).
- Since PAM session modules are run as root, we can turn pam_limits back
on by default, and it no longer spits out "Operation not permitted" to
syslog (closes: #171673).
- Password expiry works again (closes: #153235).
- 'ssh -q' suppresses login banner (closes: #134589).
- sshd doesn't lie to PAM about invalid usernames (closes: #157078).
- ssh-add prints key comment on each prompt (closes: #181869).
- Punctuation formatting fixed in man pages (closes: #191131).
- EnableSSHKeysign documented in ssh_config(5) (closes: #224457).
* Add 'UsePAM yes' to /etc/ssh/sshd_config on upgrade from versions older
than this, to maintain the standard Debian sshd configuration.
* Comment out PAMAuthenticationViaKbdInt and RhostsAuthentication in
sshd_config on upgrade. Neither option is supported any more.
* Privilege separation and PAM are now properly supported together, so
remove both debconf questions related to them and simply set it
unconditionally in newly generated sshd_config files (closes: #228838).
* ServerAliveInterval implemented upstream, so ProtocolKeepAlives is now a
compatibility alias. The semantics differ slightly, though; see
ssh_config(5) for details.
* Implement SSH1 support for ServerAliveInterval using SSH_MSG_IGNORE. As
documented in ssh_config(5), it's not as good as the SSH2 version.
* Remove -fno-builtin-log, -DHAVE_MMAP_ANON_SHARED, and
-D__FILE_OFFSET_BITS=64 compiler options, which are no longer necessary.
* Update config.guess and config.sub from autotools-dev 20040105.1.

- Reset signal status when starting pam auth thread, prevent hanging
during PAM keyboard-interactive authentications.
- Fix a non-security-critical segfault in PAM authentication.

openssh (1:3.6.1p2-1) unstable; urgency=medium
* New upstream release, including fix for PAM user-discovery security hole
(closes: #191681).
* Fix ChallengeResponseAuthentication default in generated sshd_config
(closes: #106037).
* Put newlines after full stops in man page documentation for
ProtocolKeepAlives and SetupTimeOut.
* Policy version 3.5.9: support DEB_BUILD_OPTIONS=noopt, build
gnome-ssh-askpass with -g and -Wall flags.
* Really ask ssh/new_config debconf question before trying to fetch its
value (closes: #188721).
* On purge, remove only the files we know about in /etc/ssh rather than
the whole thing, and remove the directory if that leaves it empty
(closes: #176679).
* ssh has depended on debconf for some time now with no complaints, so:
- Simplify the postinst by relying on debconf being present. (The absent
case was buggy anyway.)
- Get rid of "if you have not installed debconf" text in README.Debian,
and generally update the "/usr/bin/ssh not SUID" entry.
* More README.Debian work:
- Reorganize into "UPGRADE ISSUES" and "OTHER ISSUES", in an effort to
make it easier for people to find the former. The upgrade issues
should probably be sorted by version somehow.
- Document X11UseLocalhost under "X11 Forwarding" (closes: #150913).
* Fix setting of IP flags for interactive sessions (upstream bug #541).

openssh (1:3.6.1p1-1) unstable; urgency=low

-- Colin Watson <cjwatson@debian.org> Wed, 2 Apr 2003 00:51:02 +0100
openssh (1:3.6p1-1) unstable; urgency=low
* New upstream release.
- Workaround applied upstream for a bug in the interaction of glibc's
getaddrinfo() with the Linux 2.2 kernel (closes: #155814).
- As such, it should now be safe to remove --with-ipv4-default, so
starting sshd with -6 is no longer necessary (closes: #79861 and lots
of other merged bugs).
- ssh-copy-id prints usage when run without arguments (closes: #71376).
- scp exits 1 if ssh fails (closes: #138400).
- sshd writes to utmp's ut_addr_v6 field in IPv6 mode (closes: #167867).
- 'ssh-add -c' causes ssh-agent to ask the user each time a key is used
(closes: #109795).
* Install /etc/default/ssh non-executable (closes: #185537).
-- Colin Watson <cjwatson@debian.org> Mon, 31 Mar 2003 23:00:59 +0100
openssh (1:3.5p1-5) unstable; urgency=low
* Add /etc/default/ssh (closes: #161049).
* Run the init script under 'set -e' (closes: #175010).
* Change the default superuser path to include /sbin, /usr/sbin, and
/usr/local/sbin (closes: #128235, #151267). Using login.defs would be
nice, but that belongs to another package. Without a defined API to
retrieve its settings, parsing it is off-limits.
* Build ssh-askpass-gnome with GNOME 2. The source package should still
support building on stable with GNOME 1, using the alternate
libgnome-dev build-dependency (thanks, Colin Walters; closes: #167582).
-- Colin Watson <cjwatson@debian.org> Sun, 9 Mar 2003 20:12:10 +0000
openssh (1:3.5p1-4) unstable; urgency=low
* Point rlogin and rcp alternatives at slogin and scp respectively rather
than ssh (closes: #121103, #151666). Fix alternative removal to match;
previously it was completely wrong anyway.
* Find out whether /etc/ssh/sshd_not_to_be_run exists and set the debconf
question's default using that information, rather than using debconf as
a registry. Other solutions may be better in the long run, but this is
at least correct (thanks, Matthew Woodcraft; closes: #84725).
* Stop using pam_lastlog, as it doesn't currently work well as a session
module when privilege separation is enabled; it can usually read
/var/log/lastlog but can't write to it. Instead, just use sshd's
built-in support, already enabled by default (closes: #151297, #169938).
* Use 'ssh-keygen -q' rather than redirecting output to /dev/null.
* Add a "this may take some time" warning when creating host keys on
installation (part of #110094).
* When restarting via the init script, check for sshd_not_to_be_run after
stopping sshd (idea from Tomas Pospisek; closes: #149850).
* Append /usr/sbin:/sbin to the init script's $PATH, just in case of
strangeness (closes: #115138).
* Fix a dpkg-statoverride call to redirect stdout to /dev/null, not
stderr.
* Correct copyright file typo: "orignal" -> "original" (closes: #176490).
* Rebuild with libssl0.9.7 (closes: #176983).
* We're up to policy version 3.5.6. DEB_BUILD_OPTIONS stuff still needs to
be looked at.

openssh (1:3.5p1-3) unstable; urgency=low
* Happy new year!
* Use getent rather than id to find out whether the sshd user exists
(closes: #150974).
* Remove some duplication from the postinst's ssh-keysign setuid code.
* Replace db_text with db_input throughout debian/config. (db_text has
been a compatibility wrapper since debconf 0.1.5.)
* Warn about PermitUserEnvironment on upgrade (closes: #167895).
* Use 'make install-nokeys', and disable unused debhelper commands,
thereby forward-porting the last pieces of Zack Weinberg's patch
(closes: #68341).
* Move the man page for gnome-ssh-askpass from the ssh package to
ssh-askpass-gnome (closes: #174449).
* Build with -DLOGIN_NO_ENDOPT, since Debian's /bin/login doesn't accept
'--' to terminate the list of options (closes: #171554).
* Add Jonathan Amery's ssh-argv0 script (closes: #111341).
* Update Danish debconf template (thanks, Morten Brix Pedersen;
closes: #174757).
* Document setgid ssh-agent's effect on certain environment variables in
README.Debian (closes: #167974).
* Document interoperability problems between scp and ssh.com's server in
README.Debian, and suggest some workarounds (closes: #174662).

openssh (1:3.5p1-2) unstable; urgency=low
* Mention in the ssh package description that it provides both ssh and
sshd (closes: #99680).

-- Colin Watson <cjwatson@debian.org> Mon, 4 Nov 2002 13:43:53 +0000
openssh (1:3.5p1-1) unstable; urgency=low
* New upstream release.
- Fixes typo in ssh-add usage (closes: #152239).
- Fixes 'PermitRootLogin forced-commands-only' (closes: #166184).
- ~/.ssh/environment and environment= options in ~/.ssh/authorized_keys
are deprecated for security reasons and will eventually go away. For
now they can be re-enabled by setting 'PermitUserEnvironment yes' in
sshd_config.
- ssh-agent is installed setgid to prevent ptrace() attacks. The group
actually doesn't matter, as it drops privileges immediately, but to
avoid confusion the postinst creates a new 'ssh' group for it.
* Obsolete patches:
- Solar Designer's privsep+compression patch for Linux 2.2 (see
1:3.3p1-0.0woody1).
- Hostbased auth ssh-keysign backport (see 1:3.4p1-4).
* Remove duplicated phrase in ssh_config(5) (closes: #152404).
* Source the debconf confmodule at the top of the postrm rather than at
the bottom, to avoid making future non-idempotency problems worse (see
#151035).
* Debconf templates:
- Add Polish (thanks, Grzegorz Kusnierz).
- Update French (thanks, Denis Barbier; closes: #132509).
- Update Spanish (thanks, Carlos Valdivia Yagüe; closes: #164716).
* Write a man page for gnome-ssh-askpass, and link it to ssh-askpass.1 if
this is the selected ssh-askpass alternative (closes: #67775).

* Drop ssh-askpass-gnome's priority to optional, per the override file.
* Drop the PAM special case for hurd-i386 (closes: #99157).
* s/dile/idle/ in ssh_config(5) (closes: #118331).
* Note in README.Debian that you need xauth from xbase-clients on the
server for X11 forwarding (closes: #140269).
* Use correct path to upstream README in copyright file (closes: #146037).
* Document the units for ProtocolKeepAlives (closes: #159479).
* Backport upstream patch to fix hostbased auth (closes: #117114).

This bug was filed on "openssh", and I ended up
creating my own patch for this (closes: #59054)
* Improved error message when ssh_exchange_identification
gets EOF (closes: #58904)
* Fixed typo (your -> you're) in debian/preinst.
* Added else-clauses to config to make this upgradepath possible:
oldssh -> openssh preinst fails due to upgrade_to_openssh=false
-> ssh-nonfree -> openssh. Without these, debconf remembered
the old answer, config didn't force asking it, and preinst always
aborted (closes: #56596, #57782)
* Moved setting upgrade_to_openssh isdefault flag to the place
where preinst would abort. This means no double question to most
users, people who currently suffer from "can't upgrade" may need
to run apt-get install ssh twice. Did not do the same for
use_old_init_script, as the situation is a bit different, and
less common (closes: #54010, #56224)
* Check for existance of ssh-keygen before attempting to use it in
preinst, added warning for non-existant ssh-keygen in config. This
happens when the old ssh is removed (say, due to ssh-nonfree getting
installed).
