Ubuntu 22.04 LTS : Sudo vulnerability (USN-5908-1)

high Nessus Plugin ID 172057

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5908-1 advisory.

 It was discovered that Sudo incorrectly handled the per-command chroot feature. In certain environments where Sudo is configured with a rule that contains a CHROOT setting, a local attacker could use this issue to cause Sudo to crash, resulting in a denial of service, or possibly escalate privileges.

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 sudo and / or sudo-ldap packages.
