Cisco FirePOWER System Software Packet Processing Denial of Service Vulnerability

A vulnerability in the packet processing functions of Cisco FirePOWER System Software could allow an unauthenticated, remote attacker to cause an affected system to stop inspecting and processing packets, resulting in a denial of service (DoS) condition.

The vulnerability is due to improper packet handling by the affected software when packets are passed through the sensing interfaces of an affected system. An attacker could exploit this vulnerability by sending crafted packets through a targeted system.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
