Ubuntu Security Notice USN-1138-2
May 27, 2011

network-manager, modemmanger update

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

- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS


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.

Update instructions:

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.
