[Bug 2006073] Re: PAM: CVE-2022-28321 patch not correctly applied

[A. Saber Shenouda]

Is Ubuntu/Linux really affected by that CVE? It really looks like it is
specific to Suse.

I tried to reproduce on ubuntu what was described in the original report
at SUSE https://bugzilla.suse.com/show_bug.cgi?id=1197654:

-:user1:ALL EXCEPT 127.0.0.1

and on ubuntu, it was the correct behaviour. Could not connect beside
via 127.0.0.1.

  While building, it picks up all patches from debian/patches-applied but not
  debian/patches. The build passes but the CVE fix is not applied.
