We have already found ways around this. There are still buffer overflow exploits for windows with all the protection set to max! On windows that is the best protection you can have. On Linux with va radomisation and the removal of jmp esp from shared objects buffer overflows get very difficult. But windows is rife with statically loaded DLL with jmp esp opcodes.
The problems are while you can set some memory to non-excicute you can not set all memory to non-excicute! So you get buffer overflows which use return to libc or ret2code. Which are never in the non-excicute section.
Remember everything is possible, no matter how hard we work to secure a system people will work just has hard to unsecure it.
