security/ipsec-tools: fix 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.
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.
