    It would be VERY helpful to post the CVE or other details in the question. That way we don't have to hunt through several layers of information to figure out what you are asking. – schroeder Apr 24 '15 at 2:44

Please look at how SipHash replaced old hash mechanism to counter-measure DoS through hash collision.
