Test ID:1.3.6.1.4.1.25623.1.0.60264
Category:Fedora Local Security Checks
Title:Fedora Core 7 FEDORA-2008-0956 (xorg-x11-server)
Summary:NOSUMMARY
Description:Description:

The remote host is missing an update to xorg-x11-server
announced via advisory FEDORA-2008-0956.

When enabling the unredirect fullscreen windows option,
compiz will unredirect fullscreen windows to improve
performace. However, unredirecting will as a side effect
break any grabs on that window, which compromises most
screensavers. This X server update suppresses this
unintended side effect and restores the security of the
screensavers. See also CVE-2007-3069.
