Descriptions
A vulnerability in the DHCP module of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the affected device. The vulnerability is due to incorrect processing of certain DHCP packets. An attacker could exploit this vulnerability by sending a crafted DHCP packet to the affected device. A successful exploit could allow the attacker to cause a DoS condition on the affected device.
Una vulnerabilidad en el módulo DHCP del Cisco Adaptive Security Appliance (ASA) Software y el Cisco Firepower Threat Defense (FTD) Software, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) sobre el dispositivo afectado. La vulnerabilidad es debido al procesamiento incorrecto de determinados paquetes DHCP. Un atacante podría explotar esta vulnerabilidad mediante el envío de un paquete DHCP diseñado hacia el dispositivo afectado. Una explotación con éxito podría permitir a un atacante causar una condición DoS sobre el dispositivo afectado.
