RHEL 2.1 / 3 : xscreensaver (RHSA-2006:0498)

medium Nessus Plugin ID 21593

Synopsis

The remote Red Hat host is missing a security update.

Description

An updated xscreensaver package that fixes two security flaws is now available for Red Hat Enterprise Linux 2.1 and 3.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

XScreenSaver is a collection of screensavers.

A keyboard focus flaw was found in the way XScreenSaver prompts the user to enter their password to unlock the screen. XScreenSaver did not properly ensure it had proper keyboard focus, which could leak a users password to the program with keyboard focus. This behavior is not common, as only certain applications exhibit this focus error.
(CVE-2004-2655)

Several flaws were found in the way various XScreenSaver screensavers create temporary files. It may be possible for a local attacker to create a temporary file in way that could overwrite a different file to which the user running XScreenSaver has write permissions.
(CVE-2003-1294)

Users of XScreenSaver should upgrade to this updated package, which contains backported patches to correct these issues.

Solution

Update the affected xscreensaver package.
