Synopsis

The remote Red Hat host is missing a security update for gnome-screensaver.

Description

The remote Redhat Enterprise Linux 5 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2008:0197 advisory.

gnome-screensaver is the GNOME project's official screen saver program.

A flaw was found in the way gnome-screensaver verified user passwords. When a system used a remote directory service for login credentials, a local attacker able to cause a network outage could cause gnome-screensaver to crash, unlocking the screen. (CVE-2008-0887)

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

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
