20 October 2015

An application using the MiniUPnP library could be made to crash or run programs as your login if it received specially crafted network traffic.



  • miniupnpc - UPnP IGD client lightweight library


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
possibly execute arbitrary code with privileges of the user running
an application that uses the MiniUPnP library.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 15.04
Ubuntu 14.04
Ubuntu 12.04

After a standard system update you need to restart applications using
the MiniUPnP library to make all the necessary changes.
