Ubuntu 7.10 : compiz vulnerability (USN-537-2)

Medium Nessus Plugin ID 28144


The remote Ubuntu host is missing one or more security-related patches.


USN-537-1 fixed vulnerabilities in gnome-screensaver. The fixes were incomplete, and only reduced the scope of the vulnerability, without fully solving it. This update fixes related problems in compiz.

Jens 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.


Update the affected packages.
