Heap-based buffer overflow in the create_url_list function in gena/gena_device.c in Portable UPnP SDK (aka libupnp) before 1.6.21 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a valid URI followed by an invalid one in the CALLBACK header of an SUBSCRIBE request.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
