Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Numerous errors in isakmpd's input packet validation lead to
denial-of-service vulnerabilities. From the Rapid7 advisory :

The ISAKMP packet processing functions in OpenBSD's isakmpd daemon
contain multiple payload handling flaws that allow a remote attacker
to launch a denial of service attack against the daemon.

Carefully crafted ISAKMP packets will cause the isakmpd daemon to
attempt out-of-bounds reads, exhaust available memory, or loop
endlessly (consuming 100% of the CPU).
