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. This crash can be triggered by sending a malformed SUBSCRIBE or UNSUBSCRIBE using any of the attached files.
For Debian 8 Jessie
, this problem has been fixed in version
1.6.19+git20141001-1+deb8u2.
We recommend that you upgrade your libupnp packages.
