Description An issue in the processing of a malformed OSPF TLV allows an unauthenticated adjacent attacker to cause the periodic packet management daemon (PPMD) process to go into an infinite loop. This can impact protocols and functions reliant on PPMD, such as OSPF neighbor reachability, resulting in a sustained Denial of Service (DoS) condition. The DoS condition persists until the PPMD process is manually restarted.
