Related CVEs CVE-2020-12695

Yunus Çadırcı found an issue in the SUBSCRIBE method of UPnP, a network protocol for devices to automatically discover and communicate with each other. Insuficient checks on this method allowed attackers to use vulnerable UPnP services for DoS attacks or possibly to bypass firewalls.

For Debian 8 jessie, these problems have been fixed in version 0.20.12-1+deb8u1.

We recommend that you upgrade your gupnp packages.
