A vulnerability exists in the isakmpd that could allow a remote attacker to cause a denial of service.
The OpenBSD isakmpd establishes security associations for encrypted and authenticated (IPsec) network traffic. It implements the Internet Security Association and Key Management Protocol (ISAKMP) and Internet Key Exchange (IKE) protocol. The ISAKMP standard specifies:
The Security Association Payload is used to negotiate security attributes and to indicate the Domain of Interpretation (DOI) and Situation under which the negotiation is taking place.
A remote attacker could cause the isakmpd service to crash. Subsequent IPsec-enabled communications may be disrupted as a result.
