NVD Description

Note: Versions mentioned in the description apply only to the upstream xscreensaver package and not the xscreensaver package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

XScreenSaver 4.10, when using a remote directory service for credentials, does not properly handle the results from the getpwuid function in drivers/lock.c when there is no network connectivity, which causes XScreenSaver to crash and unlock the screen and allows local users to bypass authentication.
