libupnp - security update

Scott Tenaglia discovered a heap-based buffer overflow in libupnp, a
portable SDK for UPnP Devices. That can lead to denial of service or
remote code execution.

For Debian 7 Wheezy, these problems have been fixed in version
1:1.6.17-1.2+deb7u2.

We recommend that you upgrade your libupnp packages.
