Buffer Overflows exploit for SunOS 4.1.4

   about one month ago, I posted here a generic exploit for buffer
overflows on SunOS 4. I didn't find a real bug which could be exploited in
a standard application so my exploit applied only to my own programs.

Now, I succeeded in getting a root shell using the X11 ressource manager
bug ('xterm -xrm xxxxxxxxxxxxxxxxxxx...xxxxxxxxx'), which isn't new, but
demonstrates that my exploit really works.

As I saw, there aren't many buffer overflow exploits for SunOS, perhaps
because of some complications.

My package includes a script which can automatically try several stack
offsets, which could be useful when testing a wrapper in development.

You can retrieve this on my web page:


Hope this can help somebody...
