More information:

The Internet Key Exchange version 1 (IKEv1) implementation in racoon from ipsec-tools, IPsec tools for Linux, try to dereference a NULL pointer under certain conditions which allows a remote attacker to cause a denial of service.

The old stable distribution (woody) does not contain ipsec-tools.

For the stable distribution (sarge) this problem has been fixed in version 0.5.2-1sarge1.

For the unstable distribution (sid) this problem has been fixed in version 0.6.3-1.

We recommend that you upgrade your racoon package.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
