NOTE: this issue has been disputed by the Ruby OpenSSL team and third parties who state that the original demonstration PoC contains errors and redundant or unnecessarily-complex code that does not appear to be related to a demonstration of the issue. As of 20140502 CVE is not aware of any public comment by the original researcher.
