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

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.
