Ubuntu 22.04 LTS / 24.04 LTS / 24.10 / 25.04 : Sudo vulnerabilities (USN-7604-1)

high Nessus Plugin ID 241066

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 24.10 / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7604-1 advisory.

 Rich Mirch discovered that Sudo incorrectly handled the host option. In environments where per-host rules are configured in the sudoers file, a local attacker could use this issue to bypass the host restrictions.
 (CVE-2025-32462)

 Rich Mirch discovered that Sudo incorrectly handled the chroot option. In environments where the sudoers file is configured to allow the chroot option, a local attacker could use this issue to run arbitrary commands as root. This issue only applied to Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04.
 (CVE-2025-32463)

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

Note that Nessus has not tested for these issues 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.
