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. The fix obtained from NetBSD CVS head with a command: cvs diff -D 2017-01-24 -D 2017-09-01 \ src/racoon/handler.h \ src/racoon/isakmp.c \ src/racoon/isakmp_frag.c \ src/racoon/isakmp_inf.c While here, add LICENSE.
