========================================================================== Ubuntu Security Notice USN-1138-2 May 27, 2011
A security issue affects these releases of Ubuntu and its derivatives:
An attacker could send crafted input to NetworkManager and ModemManager and cause them to crash.
Software Description: - modemmanager: Modem connection manager - network-manager: Network connection manager
USN-1138-1 fixed a vulnerability in DBus-GLib. NetworkManager and ModemManager required rebuilding against the updated DBus-GLib to incorporate the changes.
Original advisory details:
It was discovered that DBus-GLib did not properly verify the access flag of exported GObject properties under certain circumstances. A local attacker could exploit this to bypass intended access restrictions or possibly cause a denial of service.
The problem can be corrected by updating your system to the following package versions:
Ubuntu 10.04 LTS: libnm-glib2 0.8-0ubuntu3.2 modemmanager 0.3-0ubuntu2.2
Ubuntu 8.04 LTS: libnm-glib0 0.6.6-0ubuntu5.8.04.3
After a standard system update you need to reboot your computer to make all the necessary changes.
