A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

An attacker could send crafted input to applications using DBus-GLib and
possibly escalate privileges.

Software Description:
- dbus-glib: simple interprocess messaging system

Details:

Sebastian Krahmer and Bastien Nocera discovered that DBus-GLib did not
properly validate the message sender when the "NameOwnerChanged" signal was
received. A local attacker could possibly use this issue to escalate their
privileges.
