Import OpenSSH 9.5 (Last was OpenSSH 9.3)

OpenSSH 9.5/9.5p1 (2023-10-04)
OpenSSH 9.5 was released on 2023-10-04. It is available from the
mirrors listed at
OpenSSH is a 100% complete SSH protocol 2.0 implementation and
includes sftp client and server support.

Once again, we would like to thank the OpenSSH community for their
continued support of the project, especially those who contributed
code or patches, reported bugs, tested snapshots or donated to the
project. More information on donations may be found at:

Changes since OpenSSH 9.4

This release fixes a number of bugs and adds some small features.

Potentially incompatible changes

 * ssh-keygen(1): generate Ed25519 keys by default. Ed25519 public keys
   are very convenient due to their small size. Ed25519 keys are
   specified in RFC 8709 and OpenSSH has supported them since version 6.5
   (January 2014).

 * sshd(8): the Subsystem directive now accurately preserves quoting of
   subsystem commands and arguments. This may change behaviour for exotic
   configurations, but the most common subsystem configuration
   (sftp-server) is unlikely to be affected.

New features

 * ssh(1): add keystroke timing obfuscation to the client. This attempts
   to hide inter-keystroke timings by sending interactive traffic at
   fixed intervals (default: every 20ms) when there is only a small
   amount of data being sent. It also sends fake "chaff" keystrokes for
   a random interval after the last real keystroke. These are
   controlled by a new ssh_config ObscureKeystrokeTiming keyword.

 * ssh(1), sshd(8): Introduce a transport-level ping facility. This adds
   a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
   implement a ping capability. These messages use numbers in the "local
   extensions" number space and are advertised using a ""
   ext-info message with a string version number of "0".

 * sshd(8): allow override of Subsystem directives in sshd Match blocks.


 * scp(1): fix scp in SFTP mode recursive upload and download of
   directories that contain symlinks to other directories. In scp mode,
   the links would be followed, but in SFTP mode they were not. bz3611

 * ssh-keygen(1): handle cr+lf (instead of just cr) line endings in
   sshsig signature files.

 * ssh(1): interactive mode for ControlPersist sessions if they
   originally requested a tty.

 * sshd(8): make PerSourceMaxStartups first-match-wins

 * sshd(8): limit artificial login delay to a reasonable maximum (5s)
   and don't delay at all for the "none" authentication

 * sshd(8): Log errors in kex_exchange_identification() with level
   verbose instead of error to reduce preauth log spam. All of those
   get logged with a more generic error message by sshpkt_fatal().

 * sshd(8): correct math for ClientAliveInterval that caused the probes
    to be sent less frequently than configured.

 * ssh(1): fix regression in OpenSSH 9.4 (mux.c r1.99) that caused
   multiplexed sessions to ignore SIGINT under some circumstances.


 * Avoid clang zero-call-used-regs=all bug on Apple compilers, which
   for some reason have version numbers that do not match the upstream
   clang version numbers. bz#3584

 * Fix configure test for zlib 1.3 and later/development versions. bz3604

Changes since OpenSSH 9.3p2

This release fixes a number of bugs and adds some small features.

Potentially incompatible changes

 * This release removes support for older versions of libcrypto.
   OpenSSH now requires LibreSSL >= 3.1.0 or OpenSSL >= 1.1.1.
   Note that these versions are already deprecated by their upstream

 * ssh-agent(1): PKCS#11 modules must now be specified by their full
   paths. Previously dlopen(3) could search for them in system
   library directories.

New features

 * ssh(1): allow forwarding Unix Domain sockets via ssh -W.

 * ssh(1): add support for configuration tags to ssh(1).
   This adds a ssh_config(5) "Tag" directive and corresponding
   "Match tag" predicate that may be used to select blocks of
   configuration similar to the pf.conf(5) keywords of the same

 * ssh(1): add a "match localnetwork" predicate. This allows matching
   on the addresses of available network interfaces and may be used to
   vary the effective client configuration based on network location.

 * ssh(1), sshd(8), ssh-keygen(1): infrastructure support for KRL
   extensions.  This defines wire formats for optional KRL extensions
   and implements parsing of the new submessages. No actual extensions
   are supported at this point.

 * sshd(8): AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
   accept two additional %-expansion sequences: %D which expands to
   the routing domain of the connected session and %C which expands
   to the addresses and port numbers for the source and destination
   of the connection.

 * ssh-keygen(1): increase the default work factor (rounds) for the
   bcrypt KDF used to derive symmetric encryption keys for passphrase
   protected key files by 50%.


 * ssh-agent(1): improve isolation between loaded PKCS#11 modules
   by running separate ssh-pkcs11-helpers for each loaded provider.

 * ssh(1): make -f (fork after authentication) work correctly with
   multiplexed connections, including ControlPersist. bz3589 bz3589

 * ssh(1): make ConnectTimeout apply to multiplexing sockets and not
   just to network connections.

 * ssh-agent(1), ssh(1): improve defences against invalid PKCS#11
   modules being loaded by checking that the requested module
   contains the required symbol before loading it.

 * sshd(8): fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
   appears before it in sshd_config. Since OpenSSH 8.7 the
   AuthorizedPrincipalsCommand directive was incorrectly ignored in
   this situation. bz3574

 * sshd(8), ssh(1), ssh-keygen(1): remove vestigal support for KRL
   signatures When the KRL format was originally defined, it included
   support for signing of KRL objects. However, the code to sign KRLs
   and verify KRL signatues was never completed in OpenSSH. This
   release removes the partially-implemented code to verify KRLs.
   All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
   KRL files.

 * All: fix a number of memory leaks and unreachable/harmless integer

 * ssh-agent(1), ssh(1): don't truncate strings logged from PKCS#11
   modules; GHPR406

 * sshd(8), ssh(1): better validate CASignatureAlgorithms in
   ssh_config and sshd_config. Previously this directive would accept
   certificate algorithm names, but these were unusable in practice as
   OpenSSH does not support CA chains. bz3577

 * ssh(1): make `ssh -Q CASignatureAlgorithms` only list signature
   algorithms that are valid for CA signing. Previous behaviour was
   to list all signing algorithms, including certificate algorithms.

 * ssh-keyscan(1): gracefully handle systems where rlimits or the
   maximum number of open files is larger than INT_MAX; bz3581

 * ssh-keygen(1): fix "no comment" not showing on when running
   `ssh-keygen -l` on multiple keys where one has a comment and other
   following keys do not. bz3580

 * scp(1), sftp(1): adjust ftruncate() logic to handle servers that
   reorder requests. Previously, if the server reordered requests then
   the resultant file would be erroneously truncated.

 * ssh(1): don't incorrectly disable hostname canonicalization when
   CanonicalizeHostname=yes and ProxyJump was expicitly set to
   "none". bz3567

 * scp(1): when copying local->remote, check that the source file
   exists before opening an SFTP connection to the server. Based on


 * All: a number of build fixes for various platforms and
   configuration combinations.

 * sshd(8): provide a replacement for the SELinux matchpathcon()
   function, which is deprecated.

 * All: relax libcrypto version checks for OpenSSL >=3. Beyond
   OpenSSL 3.0, the ABI compatibility guarantees are wider (only
   the library major must match instead of major and minor in
   earlier versions).  bz#3548.

 * Tests: fix build problems for the FIDO provider module
   used in some tests.

Import OpenSSH 9.3 + the fix from p2 for the PKCS#11 remote provider
The previous version was OpenSSH 9.1

OpenSSH 9.3p2 (2023-07-19)
OpenSSH 9.3p2 was released on 2023-07-19. It is available from the
mirrors listed at
OpenSSH is a 100% complete SSH protocol 2.0 implementation and
includes sftp client and server support.

Changes since OpenSSH 9.3

This release fixes a security bug.


Fix CVE-2023-38408 - a condition where specific libaries loaded via
ssh-agent(1)'s PKCS#11 support could be abused to achieve remote
code execution via a forwarded agent socket if the following
conditions are met:

* Exploitation requires the presence of specific libraries on
  the victim system.
* Remote exploitation requires that the agent was forwarded
  to an attacker-controlled system.

Exploitation can also be prevented by starting ssh-agent(1) with an
empty PKCS#11/FIDO allowlist (ssh-agent -P '') or by configuring
an allowlist that contains only specific provider libraries.

This vulnerability was discovered and demonstrated to be exploitable
by the Qualys Security Advisory team.

In addition to removing the main precondition for exploitation,
this release removes the ability for remote ssh-agent(1) clients
to load PKCS#11 modules by default (see below).

Potentially-incompatible changes

 * ssh-agent(8): the agent will now refuse requests to load PKCS#11
   modules issued by remote clients by default. A flag has been added
   to restore the previous behaviour "-Oallow-remote-pkcs11".

   Note that ssh-agent(8) depends on the SSH client to identify
   requests that are remote. The OpenSSH >=8.9 ssh(1) client does
   this, but forwarding access to an agent socket using other tools
   may circumvent this restriction.

Changes since OpenSSH 9.2

This release fixes a number of security bugs.


This release contains fixes for a security problem and a memory
safety problem. The memory safety problem is not believed to be
exploitable, but we report most network-reachable memory faults as
security bugs.

 * 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.

 * ssh(1): Portable OpenSSH provides an implementation of the
   getrrsetbyname(3) function if the standard library does not
   provide it, for use by the VerifyHostKeyDNS feature. A
   specifically crafted DNS response could cause this function to
   perform an out-of-bounds read of adjacent stack data, but this
   condition does not appear to be exploitable beyond denial-of-
   service to the ssh(1) client.

   The getrrsetbyname(3) replacement is only included if the system's
   standard library lacks this function and portable OpenSSH was not
   compiled with the ldns library (--with-ldns). getrrsetbyname(3) is
   only invoked if using VerifyHostKeyDNS to fetch SSHFP records. This
   problem was found by the Coverity static analyzer.

New features

 * ssh-keygen(1), ssh-keyscan(1): accept -Ohashalg=sha1|sha256 when
   outputting SSHFP fingerprints to allow algorithm selection. bz3493

 * sshd(8): add a `sshd -G` option that parses and prints the
   effective configuration without attempting to load private keys
   and perform other checks. This allows usage of the option before
   keys have been generated and for configuration evaluation and
   verification by unprivileged users.


 * scp(1), sftp(1): fix progressmeter corruption on wide displays;

 * ssh-add(1), ssh-keygen(1): use RSA/SHA256 when testing usability
   of private keys as some systems are starting to disable RSA/SHA1
   in libcrypto.

 * sftp-server(8): fix a memory leak. GHPR363

 * ssh(1), sshd(8), ssh-keyscan(1): remove vestigal protocol
   compatibility code and simplify what's left.

 * Fix a number of low-impact Coverity static analysis findings.
   These include several reported via bz2687

 * ssh_config(5), sshd_config(5): mention that some options are not

 * Rework logging for the regression tests. Regression tests will now
   capture separate logs for each ssh and sshd invocation in a test.

 * ssh(1): make `ssh -Q CASignatureAlgorithms` work as the manpage
   says it should; bz3532.

 * ssh(1): ensure that there is a terminating newline when adding a
   new entry to known_hosts; bz3529


 * sshd(8): harden Linux seccomp sandbox. Move to an allowlist of
   mmap(2), madvise(2) and futex(2) flags, removing some concerning
   kernel attack surface.

 * sshd(8): improve Linux seccomp-bpf sandbox for older systems;

Changes since OpenSSH 9.1

This release fixes a number of security bugs.


This release contains fixes for two security problems and a memory
safety problem. The memory safety problem is not believed to be
exploitable, but we report most network-reachable memory faults as
security bugs.

 * 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

 * 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. bz3515

 * 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.

Potentially-incompatible changes

 * 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. Turning off the command-line
   allows platforms that support sandboxing of the ssh(1) client
   (currently only OpenBSD) to use a stricter default sandbox policy.

New features

 * 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". 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. bz#976

 * ssh(1): support dynamic remote port forwarding in escape
   command-line's -R processing. bz#3499


 * 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)

 * 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. bz3507

 * ssh(1): document use of the IdentityFile option as being usable to
   list public keys as well as private keys. GHPR352

 * sshd(8): check for and disallow MaxStartups values less than or
   equal to zero during config parsing, rather than failing later at
   runtime.  bz3489

 * 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

 * 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. bz3512.

 * sshd(8): simply 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.

 * misc: update autotools and regenerate the config files using the
   latest autotools

 * all: use -fzero-call-used-regs=used on clang 15 instead of
   -fzero-call-used-reg=all, as some versions of clang 15 have
   miscompile code when it was enabled. bz3475

 * 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. bz3483

 * misc: in the poll(2)/ppoll(2) compatibility code, avoid assuming
   the layout of fd_set.

 * sftp-server(8), ssh-agent(1): fix ptrace(2) disabling on older
   FreeBSD kernels. Some versions do not support using id 0 to refer
   to the current PID for procctl, so try again with getpid()
   explicitly before failing.

 * fix -Wstrict-prototypes in configure test code.
   Clang 16 now warns on this and legacy prototypes will be removed
   in C23. GHPR355

 * fix setres*id checks to work with clang-16. glibc
   has the prototypes for setresuid behind _GNU_SOURCE, and clang 16
   will error out on implicit function definitions. bz3497

Import OpenSSH-9.1 (previously we were on OpenSSH-9.0)

This release is focused on bug fixing.


This release contains fixes for three minor memory safety problems.
None are believed to be exploitable, but we report most memory safety
problems as potential security vulnerabilities out of caution.

 * ssh-keyscan(1): fix a one-byte overflow in SSH- banner processing.
   Reported by Qualys

 * ssh-keygen(1): double free() in error path of file hashing step in
   signing/verify code; GHPR333

 * ssh-keysign(8): double-free in error path introduced in openssh-8.9

Potentially-incompatible changes

 * The portable OpenSSH project now signs commits and release tags
   using git's recent SSH signature support. The list of developer
   signing keys is included in the repository as .git_allowed_signers
   and is cross-signed using the PGP key that is still used to sign
   release artifacts:

 * 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. bz3438

 * 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.

New features

 * 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 "" extension
   request that allows the client to obtain user/group names that
   correspond to a set of uids/gids.

 * sftp(1): use "" 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 "", 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. bz3468

 * 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; bz3429


 * 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.
   GHPR302, GHPR329

 * 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. GHPR329

 * sshd(8): improve logging of errors when opening authorized_keys
   files. bz2042

 * ssh(1): avoid multiplexing operations that could cause SIGPIPE from
   causing the client to exit early. bz3454

 * ssh_config(5), sshd_config(5): clarify that the RekeyLimit
   directive applies to both transmitted and received data. GHPR328

 * ssh-keygen(1): avoid double fclose() in error path.

 * sshd(8): log an error if pipe() fails while accepting a
   connection. bz3447

 * ssh(1), ssh-keygen(1): fix possible NULL deref when built without
   FIDO support. bz3443

 * ssh-keyscan(1): add missing *-sk types to ssh-keyscan manpage.

 * sshd(8): ensure that authentication passwords are cleared from
   memory in error paths. GHPR286

 * ssh(1), ssh-agent(1): avoid possibility of notifier code executing
   kill(-1). GHPR286

 * ssh_config(5): note that the ProxyJump directive also accepts the
   same tokens as ProxyCommand. GHPR305.

 * scp(1): do not 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. bz3431

 * ssh-keygen(1): improve error message when 'ssh-keygen -Y sign' is
   unable to load a private key; bz3429

 * 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.

 * ssh(1), sshd(8): be stricter in which characters will be accepted
   in specifying a mask length; allow only 0-9. GHPR278

 * ssh-keygen(1): avoid printing hash algorithm twice when dumping a

 * 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. GHPR287


 * ssh(1), ssh-keygen(1), sshd(8): automatically enable the built-in
   FIDO security key support if libfido2 is found and usable, unless
   --without-security-key-builtin was requested.

 * ssh(1), ssh-keygen(1), sshd(8): many fixes to make the WinHello
   FIDO device usable on Cygwin. The windows://hello FIDO device will
   be automatically used by default on this platform unless requested
   otherwise, or when probing resident FIDO credentials (an operation
   not currently supported by WinHello).

 * Portable OpenSSH: remove workarounds for obsolete and unsupported
   versions of OpenSSL libcrypto. In particular, this release removes
   fallback support for OpenSSL that lacks AES-CTR or AES-GCM.

   Those AES cipher modes were added to OpenSSL prior to the minimum
   version currently supported by OpenSSH, so this is not expected to
   impact any currently supported configurations.

 * sshd(8): fix SANDBOX_SECCOMP_FILTER_DEBUG on current Linux/glibc

 * All: resync and clean up internal CSPRNG code.

 * scp(1), sftp(1), sftp-server(8): avoid linking these programs with
   unnecessary libraries. They are no longer linked against libz and
   libcrypto. This may be of benefit to space constrained systems
   using any of those components in isolation.

 * sshd(8): add AUDIT_ARCH_PPC to supported seccomp sandbox

 * configure: remove special casing of crypt(). configure will no
   longer search for crypt() in libcrypto, as it was removed from
   there years ago. configure will now only search libc and libcrypt.

 * configure: refuse to use OpenSSL 3.0.4 due to potential RCE in its
   RSA implementation (CVE-2022-2274) on x86_64.

Import OpenSSH 8.9.

Future deprecation notice

A near-future release of OpenSSH will switch scp(1) from using the
legacy scp/rcp protocol to using SFTP by default.

Legacy scp/rcp performs wildcard expansion of remote filenames (e.g.
"scp host:* .") through the remote shell. This has the side effect of
requiring double quoting of shell meta-characters in file names
included on scp(1) command-lines, otherwise they could be interpreted
as shell commands on the remote side.

This creates one area of potential incompatibility: scp(1) when using
the SFTP protocol no longer requires this finicky and brittle quoting,
and attempts to use it may cause transfers to fail. We consider the
removal of the need for double-quoting shell characters in file names
to be a benefit and do not intend to introduce bug-compatibility for
legacy scp/rcp in scp(1) when using the SFTP protocol.

Another area of potential incompatibility relates to the use of remote
paths relative to other user's home directories, for example -
"scp host:~user/file /tmp". The SFTP protocol has no native way to
expand a ~user path. However, sftp-server(8) in OpenSSH 8.7 and later
support a protocol extension "" to support

Security Near Miss

 * 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.

   This situation is not exploitable because of independent checks in
   the privilege separation monitor. Privilege separation has been
   enabled by default in since openssh-3.2.2 (released in 2002) and
   has been mandatory since openssh-7.5 (released in 2017). Moreover,
   portable OpenSSH has used toolchain features available in most
   modern compilers to abort on signed integer overflow since
   openssh-6.5 (released in 2014).

   Thanks to Malcolm Stagg for finding and reporting this bug.

Potentially-incompatible changes

 * sshd(8), portable OpenSSH only: this release removes in-built
   support for MD5-hashed passwords. If you require these on your
   system then we recommend linking against libxcrypt or similar.

 * This release modifies the FIDO security key middleware interface
   and increments SSH_SK_VERSION_MAJOR.

Changes since OpenSSH 8.8

This release includes a number of new features.

New features

 * 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)
   A detailed description of the feature is available at and the protocol
   extensions are documented in the PROTOCOL and PROTOCOL.agent
   files in the source release.

 * ssh(1), sshd(8): add the 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

 * 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. PR#277.

 * 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. bz3360

 * 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; bz3375

 * 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. bz3375

 * 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

 * 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"; bz#3364

 * 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. bz3366

 * ssh(1), sshd(8): correct value for IPTOS_DSCP_LE. It needs to
   allow for the preceding two ECN bits. bz#3373

 * ssh-keygen(1): add missing -O option to usage() for the "-Y sign"

 * 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

 * ssh-agent(1): fix memleak in process_extension(); oss-fuzz
   issue #42719

 * ssh(1): suppress "Connection to xxx closed" messages when LogLevel
   is set to "error" or above. bz3378

 * ssh(1), sshd(8): use correct zlib flags when inflate(3)-ing
   compressed packet data. bz3372

 * 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 PR#289

 * 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. PR#295

 * 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.  bz#3349,

 * OS X poll(2) is broken; use compat replacement. For character-
   special devices like /dev/null, Darwin's poll(2) returns POLLNVAL
   when polled with POLLIN. Apparently this is Apple bug 3710161 -
   not public but a websearch will find other OSS projects
   rediscovering it periodically since it was first identified in

 * Correct handling of exceptfds/POLLPRI in our select(2)-based
   poll(2)/ppoll(2) compat implementation.

 * Cygwin: correct checking of mbstowcs() return value.

 * Add a basic that refers people to the

 * Enable additional compiler warnings and toolchain hardening flags,
   including -Wbitwise-instead-of-logical, -Wmisleading-indentation,
   -fzero-call-used-regs and -ftrivial-auto-var-init.

 * HP/UX. Use compat getline(3) on HP-UX 10.x, where the libc version
   is not reliable.

OpenSSH 8.5/8.5p1 (2021-03-03)

OpenSSH 8.5 was released on 2021-03-03. It is available from the
mirrors listed at
OpenSSH is a 100% complete SSH protocol 2.0 implementation and
includes sftp client and server support.

Once again, we would like to thank the OpenSSH community for their
continued support of the project, especially those who contributed
code or patches, reported bugs, tested snapshots or donated to the
project. More information on donations may be found at:

Future deprecation notice

It is now possible[1] to perform chosen-prefix attacks against the
SHA-1 algorithm for less than USD$50K.

In the SSH protocol, the "ssh-rsa" signature scheme uses the SHA-1
hash algorithm in conjunction with the RSA public key algorithm.
OpenSSH will disable this signature scheme by default in the near

Note that the deactivation of "ssh-rsa" signatures does not necessarily
require cessation of use for RSA keys. In the SSH protocol, keys may be
capable of signing using multiple algorithms. In particular, "ssh-rsa"
keys are capable of signing using "rsa-sha2-256" (RSA/SHA256),
"rsa-sha2-512" (RSA/SHA512) and "ssh-rsa" (RSA/SHA1). Only the last of
these is being turned off by default.

This algorithm is unfortunately still used widely despite the
existence of better alternatives, being the only remaining public key
signature algorithm specified by the original SSH RFCs that is still
enabled by default.

The better alternatives include:

 * The RFC8332 RSA SHA-2 signature algorithms rsa-sha2-256/512. These
   algorithms have the advantage of using the same key type as
   "ssh-rsa" but use the safe SHA-2 hash algorithms. These have been
   supported since OpenSSH 7.2 and are already used by default if the
   client and server support them.

 * The RFC8709 ssh-ed25519 signature algorithm. It has been supported
   in OpenSSH since release 6.5.

 * The RFC5656 ECDSA algorithms: ecdsa-sha2-nistp256/384/521. These
   have been supported by OpenSSH since release 5.7.

To check whether a server is using the weak ssh-rsa public key
algorithm, for host authentication, try to connect to it after
removing the ssh-rsa algorithm from ssh(1)'s allowed list:

    ssh -oHostKeyAlgorithms=-ssh-rsa user@host

If the host key verification fails and no other supported host key
types are available, the server software on that host should be

This release enables the UpdateHostKeys option by default to assist
the client by automatically migrating to better algorithms.

[1] "SHA-1 is a Shambles: First Chosen-Prefix Collision on SHA-1 and
    Application to the PGP Web of Trust" Leurent, G and Peyrin, T


 * ssh-agent(1): fixed a double-free memory corruption that was
   introduced in OpenSSH 8.2 . We treat all such memory faults as
   potentially exploitable. This bug could be reached by an attacker
   with access to the agent socket.

   On modern operating systems where the OS can provide information
   about the user identity connected to a socket, OpenSSH ssh-agent
   and sshd limit agent socket access only to the originating user
   and root. Additional mitigation may be afforded by the system's
   malloc(3)/free(3) implementation, if it detects double-free

   The most likely scenario for exploitation is a user forwarding an
   agent either to an account shared with a malicious user or to a
   host with an attacker holding root access.

 * Portable sshd(8): Prevent excessively long username going to PAM.
   This is a mitigation for a buffer overflow in Solaris' PAM username
   handling (CVE-2020-14871), and is only enabled for Sun-derived PAM
   implementations.  This is not a problem in sshd itself, it only
   prevents sshd from being used as a vector to attack Solaris' PAM.
   It does not prevent the bug in PAM from being exploited via some
   other PAM application. GHPR212

Potentially-incompatible changes

This release includes a number of changes that may affect existing

 * ssh(1), sshd(8): this release changes 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. The connection phase of
   the SSH session is time-sensitive and often explicitly interactive.
   The ultimate interactive/bulk TOS/DSCP will be set after
   authentication completes.

 * ssh(1), sshd(8): remove the pre-standardization cipher It is an alias for aes256-cbc before
   it was standardized in RFC4253 (2006), has been deprecated and
   disabled by default since OpenSSH 7.2 (2016) and was only briefly
   documented in ssh.1 in 2001.

 * ssh(1), sshd(8): update/replace the experimental post-quantum
   hybrid key exchange method based on Streamlined NTRU Prime coupled
   with X25519.

   The previous method is
   replaced with Per its
   designers, the sntrup4591761 algorithm was superseded almost two
   years ago by sntrup761.

   (note this both the updated method and the one that it replaced are
   disabled by default)

 * 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.

Changes since OpenSSH 8.4

New features

 * ssh(1): this release enables UpdateHostkeys by default subject to
   some conservative preconditions:
    - The key was matched in the UserKnownHostsFile (and not in the
    - 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

 * ssh(1), sshd(8): add a new LogVerbose configuration directive for
   that allows forcing maximum debug logging by file/function/line

 * 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. bz#3224

 * sshd(8): fix sshd_config SetEnv directives located inside Match
   blocks. GHPR201

 * 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. bz#3229

 * 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. bz#3253

 * ssh(1), sshd(8): similarly, rename HostbasedKeyTypes (ssh) and
   HostbasedAcceptedKeyTypes (sshd) to HostbasedAcceptedAlgorithms.

 * sftp-server(8): add missing 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 (oss-fuzz #30078).

 * sftp(1): allow the full range of UIDs/GIDs for chown/chgrp on 32bit
   platforms instead of being limited by LONG_MAX. bz#3206

 * Minor man page fixes (capitalization, commas, etc.) bz#3223

 * 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. bz#3222

 * 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. bz#2320

 * sshd_config(5): mention that DisableForwarding is valid in a
   sshd_config Match block. bz3239

 * sftp(1): fix incorrect sorting of "ls -ltr" under some
   circumstances. bz3248.

 * ssh(1), sshd(8): fix potential integer truncation of (unlikely)
   timeout values. bz#3250

 * 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. bz#3232 bz#3260

 * sshd(8): remove debug message from sigchld handler that could cause
   deadlock on some platforms. bz#3259

 * Sync contrib/ssh-copy-id with upstream.

 * unittests: add a hostname function for systems that don't have it.
   Some systems don't have a hostname command (it's not required by
   POSIX). The do have uname -n (which is), but not all of those have
   it report the FQDN.
