Ubuntu 7.10 : gnome-screensaver vulnerability (USN-537-1)
Medium Nessus Plugin ID 28143
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionJens Askengren discovered that gnome-screensaver became confused when running under Compiz, and could lose keyboard lock focus. A local attacker could exploit this to bypass the user's locked screen saver.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected gnome-screensaver package.
