That was released on to exploitwatch.org

Has this guy found a way to escape the heap cleanly? Comments?

Hi,

you could work with this:

--START--
#!/bin/sh
#
# The JPEG vuln is triggered by the 0 or 1 length field with an integer
flaw
# The crafted JPEG header makes Windows crash a couple of different ways
#     1) First, it crashes when the image is opened.
#     2) Second, it crashes when hovering the mouse over the image.
#
# The pointer overwrite is pretty straight forward in a debugger
#
# Usage: 
#    sh ms04-028.sh > clickme.jpg
#
# Note: This isn't a ./hack
#     - Plug in shellcode and get the address
#    - You non-kiddies out there are smart enough to fill in the blanks
#    - Until you do the above, it's just a stupid PoC crash
#
# It's ugly, but it works :)
#
# -perplexy-
