CVE-2015-6359

Estado: ModificadaMedia (6.1)—

La implementación del protocolo Neighbor Discovery (ND) en la pila IPv6 en Cisco IOS 15.3(3)S0.1 en dispositivos ASR no maneja adecuadamente las tablas internas, lo que permite a atacantes remotos causar una denegación de servicio (consumo de memoria o caída del dispositivo) a través de una inundación de mensajes ND manipulados, también conocido como Bug ID CSCup28217.
