CentOS Errata and Security Advisory CESA-2007:0322

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.
