The vulnerability is due to a memory handling error when GRE over IPv6 traffic is processed. An attacker could exploit this vulnerability by sending crafted GRE over IPv6 packets with either IPv4 or IPv6 payload through an affected device. A successful exploit could allow the attacker to cause the device to crash, resulting in a DoS condition."},{"lang":"es","value":"Una vulnerabilidad en la funcionalidad de descapsulación de túnel generic routing encapsulation (GRE) del Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. La vulnerabilidad es debido a un error de manejo de la memoria cuando es procesada la GRE sobre el tráfico IPv6. Un atacante podría explotar esta vulnerabilidad mediante el envío de paquetes GRE sobre IPv6 diseñados con carga útil de IPv4 o IPv6 a través de un dispositivo afectado. Una explotación con éxito podría permitir a un atacante causar que el dispositivo se bloquee, resultando en una condición
