MEDIA
Tipo:

Descripción
La función asn1_get_length_der en decoding.c en GNU libtasn1 antes de v2.12, tal y como se usa en GnuTLS antes del v3.0.16 y otros productos, no maneja adecuadamente ciertos valores de longitud demasiado grandes, lo que permite a atacantes remotos provocar una denegación de servicio (corrupción de la pila de memoria y caída de la aplicación) o posiblemente tener un impacto no especificado a través de una estructura ASN.1 especificamente elaborada para este fin.
