https://notcve.org/view.php?id=CVE-2003-0567
25 Jul 2003 — Cisco IOS 11.x and 12.0 through 12.2 allows remote attackers to cause a denial of service (traffic block) by sending a particular sequence of IPv4 packets to an interface on the device, causing the input queue on that interface to be marked as full. Cisco IOS 11.x y 12.0 a 12.2 permite a atacantes remotos causar una denegación de servicio (bloqueo de tráfico) enviando una cierta secuencia de paquetes IPv4 a una interfaz del dispositivo, causando que la cola de entrada de ese interfaz sea marcada como llena. • https://www.exploit-db.com/exploits/60 • CWE-20: Improper Input Validation •
