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.


Same way you exploit it on any other system that has a non-exec stack - using
a return-to-libc or other similar workaround....


It's harder then you think, there's tons of NULL's to work around
