Estado: ModificadaAlta (7.1)—

La implementación Zone-Based Firewall en Cisco IOS 12.4(122)T y anteriores no maneja correctamente las estructuras de objetos de sesiones, lo que permite a atacantes remotos causar una denegación de servicio (recarga de dispositivo) a través de trafico manipulado de la red, también conocido como Bug ID CSCul65003.
