Ubuntu 22.04 LTS / 24.04 LTS / 25.10 : Sudo vulnerability (USN-8092-1)

info Nessus Plugin ID 302218

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 host has packages installed that are affected by a vulnerability as referenced in the USN-8092-1 advisory.

 It was discovered that Sudo incorrectly checked return codes when dropping privileges to run the mailer. A local attacker could possibly use this issue to 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 libnss-sudo, sudo and / or sudo-ldap packages.
