RHEL 5 : compiz (RHSA-2008:0485)
Medium Nessus Plugin ID 32427
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated compiz packages that prevent Compiz from breaking screen saver grabs are now available for Red Hat Enterprise Linux 5.
This update has been rated as having low security impact by the Red Hat Security Response Team.
Compiz is an OpenGL-based window and compositing manager.
Most screen savers create a top-level fullscreen window to cover the desktop, and grab the input with that window. Compiz has an option to un-redirect that window, but in some cases, this breaks the grab and compromises the locked screen. (CVE-2007-3920)
Users of compiz are advised to upgrade to these updated packages, which remove this option to resolve this issue.
SolutionUpdate the affected compiz and / or compiz-devel packages.
