Description
A vulnerability in the Open Shortest Path First (OSPF) implementation of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to improper memory protection mechanisms while processing certain OSPF packets. An attacker could exploit this vulnerability by sending a series of malformed OSPF packets in a short period of time to an affected device. A successful exploit could allow the attacker to cause a reload of the affected device, resulting in a DoS condition for client traffic that is traversing the device.
