The weakness is caused due to the "gdk_window_begin_implicit_paint()" function in gdk/gdkwindow.c potentially trying to paint on non-existent foreign windows. This can lead to e.g. a crash in gnome-screensaver, which can be exploited to bypass the screen lock. The weakness is reported in version 2.18.4. Other versions may also be affected. SOLUTION: Update to version 2.18.5. PROVIDED AND/OR DISCOVERED BY: Crashes reported by e.g. Richard Ssekibuule and various others.
