The device may need to be manually reloaded to clear this Interface Forwarding Denial of Service condition. The vulnerability is due to the failure to properly check that the length of a packet to transmit does not exceed the maximum supported length of the network interface card (NIC). An attacker could exploit this vulnerability by sending a crafted IP packet or a series of crafted IP fragments through an interface on the targeted device. A successful exploit could allow the attacker to cause the network interface to cease forwarding packets. This vulnerability could be triggered by either IPv4 or IPv6 network traffic. This vulnerability affects the following Cisco products when they are running the StarOS operating system and a virtual interface card is installed on the device: Aggregation Services Router (ASR) 5700 Series, Virtualized Packet Core-Distributed Instance (VPC-DI) System Software, Virtualized Packet Core-Single Instance (VPC-SI) System Software.

Podr\u00eda ser necesario recargar manualmente el dispositivo para limpiar su condici\u00f3n de denegaci\u00f3n de servicio (DoS) de reenv\u00edo de interfaz. La vulnerabilidad se debe al error a la hora de procesar adecuadamente que la longitud de un paquete que se va a transmitir no exceda el tama\u00f1o m\u00e1ximo soportado de la tarjeta de interfaz de red (NIC). Un atacante podr\u00eda explotar esta vulnerabilidad enviando un paquete IP manipulado o una serie de fragmentos de IP manipulados a trav\u00e9s de una interfaz en el dispositivo objetivo. Su explotaci\u00f3n con \u00e9xito podr\u00eda permitir que el atacante consiga que la interfaz de red deje de reenviar paquetes. Esta vulnerabilidad podr\u00eda ser desencadenada por el tr\u00e1fico de red IPv4 o IPv6.
