The XLOCALEDIR vulnerability in XScreenSaver versions <=4.08 which allowed local users to run any command as root by creating a special XLOCALEDIR environment variable and running xscreensaver is not even close to being as funny or embarrassing as the any long password that is long enough unlocks it blunder.
You could simply type anything longer than 80 characters into the password field of a machine locked with XScreenSaver to make XScreenSaver crash and, in effect, unlock the machine. XScreenSaver had a buffer overflow bug in the password field handler from its release in 1992 until 1998.

XScreenSaver is a fine screen locker for those who use IceWM, Fluxbox and things like that and it is also a great alternative to the screensavers bundled with MATE and Xfce. GNOME and KDE Plasma have dropped support for interesting screensavers in favor of a bank screen or, in KDEs case, a dull and soul-less lock-screen. It is still somewhat relevant today even though all the major desktop environments (Cinnamon, GNOME, KDE Plasma, MATE and Xfce) come with their own screensaver programs since MATE and Xfce use screensavers from XScreenSaver.
