New openssh packages are available for Slackware 15.0 and -current to
fix security issues.
Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/openssh-10.4p1-i586-1_slack15.0.txz: Upgraded.
This release contains a number of security fixes:
sftp(1): when downloading files on the command-line using
"sftp host:/path .", a malicious server could cause the file to
be downloaded to an unexpected location. This issue was identified
by the Swival Security Scanner.
scp(1): when copying files between two remote destinations, do
not allow a malicious server to write files to the parent
directory of the intended target directory. This issue was
identified by the Swival Security Scanner.
sshd(8): when using the "internal-sftp" SFTP server implementation
(this is not the default), long command lines were previously
truncated silently after the 9th argument. If a security-relevant
option was in the 10th or later position, it would be discarded.
Reported by Steve Caffrey.
sshd(8): add a documentation note to mention that the
GSSAPIStrictAcceptorCheck option is ineffective when the server
is joined to a Windows Active Directory. Reported by Yarin Aharoni
of Safebreach.
sshd(8): DisableForwarding=yes didn't override PermitTunnel=yes
as it was documented to do. Note that PermitTunnel is not enabled
by default. Reported independently by Huzaifa Sidhpurwala of
Redhat and Marko Jevtic.
sshd(8): avoid a potential pre-authentication denial of service
when GSSAPIAuthentication was enabled (this feature is off by
default). This was not mitigated by MaxAuthTries, but would be
penalised by PerSourcePenalties. This was reported by Manfred
Kaiser of the milCERT AT (Austrian Ministry of Defence).
sshd(8): fix a number of cases where the minimum authentication
delay was not being enforced. Reported by the Orange Cyberdefense
Vulnerability Team.
ssh(1): fix a possible client-side use-after-free if the server
changes its host key during a key reexchange. This was reported by
Zhenpeng (Leo) Lin of Depthfirst.
