Try this artice: http://www.phrack.org/show.php?p=57&a=5 for 64-bit
code, and this article http://www.phrack.org/show.php?p=58&a=4 for
non-stack exploit techniques.

Hope this helps.

Subject: Exploiting Buffer Overflows on Compaq Tru64 and No-Exec
Stack


Hi,

I have been testing buffer overflows on Compaq Tru64. However, all my
examples execute code on the stack. Tru64 comes with a default 
non-executable stack.

How can one exploit a Tru64 buffer overflow without executing code on
the 
stack ? I would appreciate any techniques / White papers or coding
examples 
that I can use to further my understanding of these issues in a
64-bit 
environment.

Thanks in advance for any help, Helm
