3. Description:

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.

4. Solution:

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
