Release notes are available at https://www.openssh.com/txt/release-9.1 9.1 contains fixes for three minor memory safety problems; these have lready been merged to the copy of OpenSSH 9.0 that is in the FreeBSD base system. Some highlights copied from the release notes: Potentially-incompatible changes -------------------------------- * 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). * 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. 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 MFC after: 2 weeks Relnotes: Yes Sponsored by: The FreeBSD Foundation

|
|
This is the port of OpenBSD's excellent OpenSSH[0] to Linux and other
|
|
Unices.
|
|
|
|
OpenSSH is based on the last free version of Tatu Ylonen's sample
|
|
implementation with all patent-encumbered algorithms removed (to
|
|
external libraries), all known security bugs fixed, new features
|
|
reintroduced and many other clean-ups. OpenSSH has been created by
|
|
Aaron Campbell, Bob Beck, Markus Friedl, Niels Provos, Theo de Raadt,
|
|
and Dug Song. It has a homepage at https://www.openssh.com/
|
|
|
|
This port consists of the re-introduction of autoconf support, PAM
|
|
support, EGD/PRNGD support and replacements for OpenBSD library
|
|
functions that are (regrettably) absent from other unices. This port
|
|
has been best tested on AIX, Cygwin, HP-UX, Linux, MacOS/X,
|
|
FreeBSD, NetBSD, OpenBSD, OpenServer, Solaris and UnixWare.
|
|
|
|
This version actively tracks changes in the OpenBSD CVS repository.
|
|
|
|
The PAM support is now more functional than the popular packages of
|
|
commercial ssh-1.2.x. It checks "account" and "session" modules for
|
|
all logins, not just when using password authentication.
|
|
|
|
There is now several mailing lists for this port of OpenSSH. Please
|
|
refer to https://www.openssh.com/list.html for details on how to join.
|
|
|
|
Please send bug reports and patches to https://bugzilla.mindrot.org or
|
|
the mailing list openssh-unix-dev@mindrot.org. To mitigate spam, the
|
|
list only allows posting from subscribed addresses. Code contribution
|
|
are welcomed, but please follow the OpenBSD style guidelines[1].
|
|
|
|
Please refer to the INSTALL document for information on dependencies and
|
|
how to install OpenSSH on your system.

Miscellania -
|
|
|
|
This version of OpenSSH is based upon code retrieved from the OpenBSD CVS
|
|
repository which in turn was based on the last free sample implementation
|
|
released by Tatu Ylonen.
