3. Problem description:

The ipsec-tools package is used in conjunction with the IPsec functionality
in the linux kernel and includes racoon, an IKEv1 keying daemon.

A denial of service flaw was found in the ipsec-tools racoon daemon.  If a
victim's machine has racoon configured in a non-recommended insecure
manner, it is possible for a remote attacker to crash the racoon daemon. 
(CVE-2005-3732)

Users of ipsec-tools should upgrade to these updated packages, which contain
backported patches, and are not vulnerable to these issues.

4. Solution:
