Comment 2 Georg Sauthoff 2023-12-21 12:32:58 UTC
Like in Fedora <= 38, a simple fix by update for this issue is blocked by upstream's python cryptography version requirements.

See also https://bugzilla.redhat.com/show_bug.cgi?id=2250331#c3 for details.

Comment 3 Carl George 🤠 2024-01-23 22:39:51 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.

Comment 7 Carl George 🤠 2024-02-20 16:22:27 UTC
In order to track EPEL8 and EPEL9 separately, I've cloned this bug to bug 2265139.  Since the EPEL9 bodhi update is linked to this one, I'm editing it to be for EPEL9 and leaving the clone for EPEL8.
