high Nessus Plugin ID 241898

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

 - Sudo before 1.9.17p1 allows local users to obtain root access because /etc/nsswitch.conf from a user- controlled directory is used with the --chroot option. (CVE-2025-32463)
