3. Problem description:

XScreenSaver is a collection of screensavers.

Alex Yamauchi discovered a flaw in the way XScreenSaver verifies user
passwords. When a system is using a remote directory service for login
credentials, a local attacker may be able to cause a network outage causing
XScreenSaver to crash, unlocking the screen. (CVE-2007-1859)

Users of XScreenSaver should upgrade to this updated package, which
contains a backported patch to correct this issue.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  

This update is available via Red Hat Network.  Details on how to use 
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/FAQ_58_10188
