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

- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

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

Software Description:
- miniupnpc: UPnP IGD client lightweight library

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
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:
  libminiupnpc10                  1.9.20140610-2ubuntu1.1

Ubuntu 14.04 LTS:
  libminiupnpc8                   1.6-3ubuntu2.14.04.2

Ubuntu 12.04 LTS:
  libminiupnpc8                   1.6-3ubuntu1.2

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