Synopsis
The remote Amazon Linux AMI host is missing a security update.Description
When an ISAKMP message with an invalid KEY_LENGTH attribute is received, the error handling function crashes on a NULL pointer dereference. Openswan automatically restarts the pluto IKE daemon but all ISAKMP state is lost. This vulnerability does NOT allow an attacker access to the system. This can be used to launch a denial of service attack by sending repeated IKE packets with the invalid key length attribute.Solution
Run 'yum upgrade openswan' to upgrade your system.See Also
