Descriptions

Cisco IOS 12.0 through 12.4 on Cisco 10000, uBR10012 and uBR7200 series devices handles external UDP packets that are sent to 127.0.0.0/8 addresses intended for IPC communication within the device, which allows remote attackers to cause a denial of service (device or linecard reload) via crafted UDP packets, a different vulnerability than CVE-2008-3805.

En Cisco IOS v12.0 a la v12.4 en Cisco 10000, los paquetes externos del UDP del manejador de dispositivos de la serie uBR10012 y uBR7200 que se envían a las direcciones 127.0.0.0 /8 pensados para comunicación IPC dentro del dispositivo, permite que los atacantes remotos causen una denegación del servicio (reinicio del dispositivo o del linecard) a través de paquetes del UDP manipulados, una vulnerabilidad distinta de CVE-2008-3805.
