Hello,

I have a custom application that I am using to learn a little more
about format string vulnerabilities. It is basically an echo server. I
have been able to exploit the vulnerability and write data to memory
on the server however the problem I am seeing is that I want to
overwrite EIP but every time the application runs the stack seems to
be at a different location.

Does anyone know if Red Hat 9 has any form of stack protection? If so
is there a way to disable it?

Mike
