(RHSA-2013:0568) Important: dbus-glib security update

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.
