    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
    
    Summary:
    
    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
    
    Details:
    
    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.
