+	  <p>The ipsec-tools racoon daemon contains a remotely exploitable computational
+	  complexity attack when parsing and storing isakmp fragments. The implementation
+	  permits a remote attacker to exhaust computational resources on the remote endpoint
+	  by repeatedly sending isakmp fragment packets in a particular order such that
+	  the worst-case computational complexity is realized in the algorithm utilized
+	  to determine if reassembly of the fragments can take place.</p>
