 This is a denial of service exploit that targets the NSA/TAO "BenignCertain" exploitation tool, the capabilities which are explained quite well over at [Mustafa Al-Bassam's blog post on the topic][musalbas].
 
 I know, I know, "No More DoS PoC's", however, upon having a more skilled at reverse engineering colleague at Xiphos examine the binary in IDA, it was determined that this bug is probably not exploitable to gain RCE.

 Anyway, I drop this PoC here for you, so you, too, can crash silly NSA toys. 
 And maybe one of you clever folks can figure out what we missed to gain RCE?
