Overview
A vulnerability exists in the isakmpd that could allow a remote attacker to cause a denial of service.
Description
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 Delete Payload contains a protocol-specific security association identifier that the sender has removed from its security association database and is, therefore, no longer valid. [...] It is possible to send multiple Security Parameter Index(es) (SPIs) in a Delete payload [...] |
Impact
A remote attacker could cause the isakmpd service to crash. Subsequent IPsec-enabled communications may be disrupted as a result. |
Solution
Apply a patch from the vendor |
