medium Nessus Plugin ID 216701

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by a vulnerability as referenced in the USN-7287-1 advisory.

 Tianjia Zhang discovered the libcap2 PAM module pam_cap incorrectly handled parsing group names in the configuration file. This could result in certain users being granted capabilities, contrary to expectations.

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
