Red Hat Product Errata RHSA-2013:0568 0 normal SHIPPED_LIVE Important: dbus-glib security update 2013-02-26 23:28:31 UTC

Description Jan Lieskovsky 2013-02-15 14:54:24 UTC 
A privilege escalation flaw was found in the way dbus-glib, the D-Bus add-on library to integrate the standard D-Bus library with the GLib thread abstraction and main loop, performed filtering of the message sender (message source subject), when the NameOwnerChanged signal was received. A local attacker could use this flaw to escalate their privileges.
