Descriptions
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.
driver/subprocs.c en XScreenSaver en versiones anteriores a 5.34 no lleva a cabo correctamente una comprobación de consistencia interna, lo que permite a atacantes físicamente próximos eludir la pantalla de bloqueo cambiando los monitores sin apagar el dispositivo.
It was discovered that unplugging one of the monitors in a multi-monitor setup can cause xscreensaver to crash. Someone with physical access to a machine could use this problem to bypass a locked session.
