It was discovered that the notify feature in gnome-screensaver could let
a local attacker read the clipboard contents of a locked session by
using Ctrl-V. (CVE-2007-6389)

Alan Matsuoka discovered that gnome-screensaver did not properly handle
network outages when using a remote authentication service. During a
network interruption, or by disconnecting the network cable, a local
