Kame Racoon Invalid Cookie Handling Remote DoS

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote server is vulnerable to a denial of service.

Description :

The remote system appears to have a problem with processing requests
with invalid cookie values. At least one VPN product (racoon)
demonstrates this flaw. Racoon is integrated with:

FreeBSD 4.0 and beyond OpenBSD 2.7 and beyond NetBSD 1.5 and beyond
BSD/OS 4.2 and beyond

However, the bug has only been verified on FreeBSD systems.

An attacker may use this flaw to disable your VPN remotely.

Solution :

If you are running racoon VPN, download and install the latest SNAP
kit from http://www.kame.net/. If you are running a non-racoon VPN
server that is crashing due to this check, consult your vendor for a
fix.

Risk factor :

Medium / CVSS Base Score : 5.0
