DoS via crafted OSPF LSU packets in Cisco Secure Firewall ASA/FTD (heap corruption)
A vulnerability in OSPF processing in Cisco Secure Firewall ASA Software and Cisco Secure FTD Software allows an authenticated adjacent attacker to trigger an unexpected device reload (denial of service). The issue is caused by insufficient input validation when processing OSPF link-state update (LSU) packets; crafted LSU packets can corrupt the heap, leading to a reload. Exploitation requires knowledge of the OSPF secret key.
