Re: non-exec stack

Here's an overflow exploit that works on a non-exec stack on x86 boxes.
It demonstrates how it is possible to thread together several libc
calls.  I have not seen any other exploits for x86 that have done this..


Non-executable stacks do not work in Solaris/x86.

It is impossible to give page level protection that prevents
execution on the x86 architecture.
