"libupnp, the portable SDK for UPnP Devices allows remote attackers to
cause a denial of service (crash) via a crafted SSDP message due to a
NULL pointer dereference in the functions FindServiceControlURLPath
and FindServiceEventURLPath in genlib/service_table/service_table.c.

For Debian 9 stretch, this problem has been fixed in version
1:1.6.19+git20160116-1.2+deb9u1.

We recommend that you upgrade your libupnp packages.
