The vulnerability is due to insufficient error handling when an affected device has reached platform limitations. An attacker could exploit this vulnerability by sending a malicious series of IP ARP messages to an affected device. A successful exploit could allow the attacker to exhaust system resources, which would eventually cause the affected device to reload."},{"lang":"es","value":"Una vulnerabilidad en la funcionalidad de Address Resolution Protocol (ARP) de IP de Cisco IOS XE Software para Cisco ASR 1000 Series Aggregation Services Routers con un Embedded Services Processor (ESP) de 20-Gbps instalado, podría permitir a un atacante adyacente no autenticado causar la recarga de un dispositivo afectado, resultando en una condición de denegación de servicio. La vulnerabilidad es debido a un manejo insuficiente de errores cuando un dispositivo afectado ha alcanzado las limitaciones de la plataforma. Un atacante podría explotar esta vulnerabilidad mediante el envío de una serie maliciosa de mensajes ARP de IP hacia un dispositivo afectado. Una explotación con éxito podría permitir al atacante agotar los recursos del sistema, lo que podría eventualmente causar que el dispositivo afectado se
