 Overlong DSC Comment Buffer Overflow Exploit

    overlong DSC Comment Buffer Overflow Exploit
    by Nine:Situations:Group::pyrokinesis
    site: http://retrogod.altervista.org/
     
    An overlong string as DSC comment (more than 42000 bytes)
    results in a direct EIP overwrite.
    Exception is first-chance so the program will never crash.
    At the moment of the redirection EAX and ESI are user-controlled.
    This portion of the buffer begins with '%' (it is the next DSC
    comment) but as you can see the resulting pattern is 
    nop-equivalent.
     
    Tested and working against xp sp3
    change the call esi if you need, must be alphabetic
    I used a "call esi" from comctl32.dll on xp sp3,
    change if needed.
     
    Usage: php 9sg_illu.php
    then double-click on the resulting 9sg.eps file
    it will bind a shell on port 4444
    change the shellcode for your needs even.
