attacker sent repeated malicious requests, the 'racoon' key exchange
server could allocate large amounts of memory, possibly leading to a
denial of service.

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
