CVE-2016-10396

The racoon daemon in IPsec-Tools 0.8.2 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.
