"Updated ipsec-tools packages that fix a bug in racoon are now
available.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

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."
