I have a set of OpenSSH fixes that I think are worth including in the
next stable update, all of which fix regressions from bullseye:
* Minor security fix to creation of template directories (#1001186,
#1064898)
* The gssapi-keyex authentication method was declared incorrectly and
was thus unusable
(https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/2053146)
* The combination of GSS-API key exchange and public key authentication
broke in some situations (#1041521, #1088248)
In addition, although this isn't a regression, I agree with the reporter
of #1088873 that backporting the sntrup761x25519-sha512 alias for that
post-quantum key algorithm is likely to be helpful for configuration
management and interoperability.
The most delicate parts here are the GSS-API key exchange patches, and
so I thought it was best to also backport the autopkgtest that we added
earlier this year to cover this area. I found that invaluable in making
sure that I hadn't missed anything substantial.
The changes are all individually rather small (especially if you
discount some git-dpm noise in debian/patches/) and have been in testing
for some time. As mentioned above, the GSS-API key exchange parts are
the most delicate, but they don't affect people who aren't using that
feature; the other changes are close to trivial.
Of course I'll update the first line of the changelog to "bookworm"
before uploading.
