A vulnerability in the Open Shortest Path First version 2 (OSPFv2) code of Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, adjacent attacker to cause the reload of the affected system. The vulnerability is due to improper handling of OSPFv2 packets. An attacker could exploit this vulnerability by sending crafted packets to the affected system. A successful exploit could cause the system to crash, resulting in a denial of service (DoS) condition. Cisco has confirmed the vulnerability and released software updates. To exploit this vulnerability, an attacker must be on the same broadcast or collision domain as the targeted system. This access requirement reduces the likelihood of a successful exploit. Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.
