How to fix?

Upgrade Debian:11 xscreensaver to version 5.34-1 or higher.

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.

driver/subprocs.c in XScreenSaver before 5.34 does not properly perform an internal consistency check, which allows physically proximate attackers to bypass the lock screen by hot swapping monitors.
