Kame Racoon Invalid Cookie Handling Remote DoS

medium Nessus Plugin ID 12121

Language:

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.
