Original Bulletin: 
   http://www.ibm.com/support/docview.wss?uid=swg22011817

Comment: Researchers have noted that CVE-2017-3736, while potentially 
         resulting in a high severity impact, is only feasible against Diffie
         Helman implementations, and would require significant skill and a 
         very specific set of conditions to exploit, resulting in Hight 
         attack complexity.
