NVD Description

Note: Versions mentioned in the description apply only to the upstream gdm3 package and not the gdm3 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

A vulnerability was discovered in gdm before 3.31.4. When timed login is enabled in configuration, an attacker could bypass the lock screen by selecting the timed login user and waiting for the timer to expire, at which time they would gain access to the logged-in user's session.
