@ktdreyer, what do you think, should asyncssh be bumped to 2.14.1 in EPEL8 to fix this?


However, I fear that RHEL8's python3-cryptography is also older than what asyncssh 2.14.1 requires ... (cf. https://bugzilla.redhat.com/show_bug.cgi?id=2250331#c3)

NB: There is also another CVE fixed in 2.14.1 (cf. https://bugzilla.redhat.com/show_bug.cgi?id=2250326),

--- Additional comment from Carl George 🤠 on 2024-01-23 22:39:55 UTC ---

The upstream commit that fixes this CVE applies cleanly to version 2.13.2 in EPEL 9.  I've prepared that as a backport patch in this pull request.

https://src.fedoraproject.org/rpms/python-asyncssh/pull-request/6

The same commit does not apply cleanly to version 2.7.0 in EPEL 8, but we should at least resolve it in EPEL 9.
