==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 23.10
- Ubuntu 23.04

- Ubuntu 20.04 LTS

Summary:

PAM could be made to stop responding if it opened a specially crafted file.

Software Description:
- pam: Pluggable Authentication Modules

Details:

Matthias Gerstner discovered that the PAM pam_namespace module incorrectly
handled special files when performing directory checks. A local attacker
could possibly use this issue to cause PAM to stop responding, resulting in
a denial of service.
