Description The issue is due to improper OSPF implementation, which can be exploited when the device receives special LSA packets, setting the LS age to MaxAge, 3600 seconds. This can lead to route table poisoning and a DoS attack.

Recommendations For each affected version, update the software to a version that is not vulnerable to this issue. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
