Descriptions

A vulnerability in the Open Shortest Path First (OSPF) implementation in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a memory leak on an affected device. The vulnerability is due to incorrect processing of certain OSPF packets. An attacker could exploit this vulnerability by sending a series of crafted OSPF packets to be processed by an affected device. A successful exploit could allow the attacker to continuously consume memory on an affected device and eventually cause it to reload, resulting in a denial of service (DoS) condition.

Una vulnerabilidad en la implementación de Open Shortest Path First (OSPF) en el Cisco Adaptive Security Appliance (ASA) Software y el Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar una pérdida de memoria sobre un dispositivo afectado. La vulnerabilidad es debido al procesamiento incorrecto de determinados paquetes OSPF. Un atacante podría explotar esta vulnerabilidad mediante el envío de una serie de paquetes OSPF diseñados para que sean procesados por un dispositivo afectado. Una explotación con éxito podría permitir a un atacante consumir continuamente la memoria sobre un dispositivo afectado y eventualmente causar que se sobrecargue, resultando en una condición de denegación de servicio (DoS).
