Ubuntu 20.04 LTS / 22.04 LTS : AppArmor vulnerability (USN-7035-1)

critical Nessus Plugin ID 207768

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-7035-1 advisory.

 It was discovered that the AppArmor policy compiler incorrectly generated looser restrictions than expected for rules allowing mount operations. A local attacker could possibly use this to bypass AppArmor restrictions in applications where some mount operations were permitted.

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.
