"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 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: https://security-tracker.debian.org/tracker/gupnp

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
