Descriptions

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.

Desbordamiento de búfer basado en memoria dinámica en la función create_url_list en gena/gena_device.c en Portable UPnP SDK (también conocido como libupnp) en versiones anteriores a 1.6.21 permite a atacantes remotos provocar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de una URl válida seguida de una inválida en la cabecera CALLBACK de una petición SUBSCRIBE.

Multiple vulnerabilities have been found in libupnp, the worst of which could lead to the execution of arbitrary code. Versions less than 1.6.21 are affected.
