Description Jan Lieskovsky 2013-02-15 09:54:24 EST
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.
