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

Original advisory details:

 Aleksandar Nikolic discovered a buffer overflow vulnerability in the
 XML parser functionality of the MiniUPnP library. A remote attacker
 could use this to cause a denial of service (application crash) or
