- Update from version 9.3p2 to 9.4p1
- Update of rootfile not required.
- The openssh check for zlib version incorrectly identifies version 1.3 as being older
than the buggy zlib version. This bug was found on the oipenssh github pull request page
but merged after openssh-9.4p1 was issued. Patch implemented to fix zlib version
identification. This and the autoconf line can be removed when the next version of
openssh is released.
- Changelog
9.4p1
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
vendors.
* 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
name.
* 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%.
Bugfixes
* 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
overflows.
* 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
GHPR#370
