OpenBSD ISAKMPD Zero Payload Length Denial Of Service Vulnerability

A remote denial of service vulnerability exists in OpenBSD's isakmpd daemon. This issue is due to a failure of the process to handle malformed ISAKMP packets.

This issue could be leveraged to cause the affected isakmpd daemon to enter an infinite loop, effectively denying service to legitimate users.

This issue was previously reported in OpenBSD isakmpd Multiple Unspecified Remote Denial Of Service Vulnerabilities (BID 9907). That BID will be retired.
