Debian DSA-965-1 : ipsec-tools - null dereference

critical Nessus Plugin ID 22831

Synopsis

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

Description

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.

Solution

Upgrade the racoon package.

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.
