Portable UPnP SDK (aka libupnp) 1.12.1 and earlier 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.
Weakness
The product dereferences a pointer that it expects to be valid but is NULL.
