Descriptions

A vulnerability in the ICMP ingress packet processing of Cisco Firepower Threat Defense (FTD) Software for Cisco Firepower 4110 appliances could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to incomplete input validation upon receiving ICMP packets. An attacker could exploit this vulnerability by sending a high number of crafted ICMP or ICMPv6 packets to an affected device. A successful exploit could allow the attacker to cause a memory exhaustion condition that may result in an unexpected reload. No manual intervention is needed to recover the device after the reload.

Una vulnerabilidad en el procesamiento de paquetes de entrada ICMP de Cisco Firepower Threat Defense (FTD) Software para dispositivos Cisco Firepower 4110, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. La vulnerabilidad es debido a una comprobación de entrada incompleta al recibir paquetes ICMP. Un atacante podría explotar esta vulnerabilidad mediante el envío de una gran cantidad de paquetes ICMP o ICMPv6 diseñados a un dispositivo afectado. Una explotación con éxito podría permitir a un atacante causar una condición de agotamiento de la memoria que puede resultar en una recarga inesperada. No se necesita ninguna intervención manual para recuperar el dispositivo después de la recarga
