Insufficient checks on this method allowed attackers to use vulnerable UPnP services for DoS attacks or possibly to bypass firewalls.

For Debian 9 stretch, this problem has been fixed in version 1.0.1-1+deb9u1.

We recommend that you upgrade your gupnp packages.

For the detailed security status of gupnp please refer to its security tracker page at: [link moved to references]
