Ubuntu 20.04 LTS / 22.04 LTS / 23.04 / 23.10 : PAM vulnerability (USN-6588-1)

medium Nessus Plugin ID 189143

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.04 / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6588-1 advisory.

 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
