A vulnerability in the implementation of Open Shortest Path First (OSPF) Link State Advertisement (LSA) functionality in Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to a memory error in OSPF. An attacker could exploit this vulnerability by sending a crafted OSPF LSA update to an affected device. A successful exploit could allow the attacker to cause the OSPF process to restart when the crafted OSPF LSA update is received, resulting in a DoS condition. Cisco has not released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
