RHEL 4 : gdm (RHSA-2007:0286)

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing a security update.

Description :

An updated gdm package that fixes a security issue and a bug is now
available.

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

Gdm (the GNOME Display Manager) is a highly configurable
reimplementation of xdm, the X Display Manager. Gdm allows you to log
into your system with the X Window System running and supports running
several different X sessions on your local machine at the same time.

Marcus Meissner discovered a race condition issue in the way Gdm
modifies the permissions on the .ICEauthority file. A local attacker
could exploit this flaw to gain privileges. Due to the nature of the
flaw, however, a successful exploitation was unlikely. (CVE-2006-1057)

This erratum also includes a bug fix to correct the pam configuration
for the audit system.

All users of gdm should upgrade to this updated package, which
contains backported patches to resolve these issues.
