Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated dbus-glib packages that fix one security issue are now
available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

dbus-glib is an add-on library to integrate the standard D-Bus library
with the GLib main loop and threading model.

A flaw was found in the way dbus-glib filtered the message sender
(message source subject) when the 'NameOwnerChanged' signal was
received. This could trick a system service using dbus-glib (such as
fprintd) into believing a signal was sent from a privileged process,
when it was not. A local attacker could use this flaw to escalate
their privileges. (CVE-2013-0292)

All dbus-glib users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. All running
applications linked against dbus-glib, such as fprintd and
NetworkManager, must be restarted for this update to take effect.
