Details

The Oulu University Secure Programming Group discovered a remote
Denial of Service vulnerability in the racoon daemon. When the daemon
is configured to use aggressive mode, then it did not check whether
the peer sent all required payloads during the IKE negotiation phase.
A malicious IPsec peer could exploit this to crash the racoon daemon.

Please be aware that racoon is not officially supported by Ubuntu, the
package is in the 'universe' component of the archive.
