NX + ASLR + PIE/RANDEXEC ;)
[oh well, someone could argue, not having bug at all.]
BTW, I don't like the statement in the paper which basically considers the
efforts into the deployment of "W^X approaches" a consequence of
understimating ret-into-* (libc/text/code chunks/gadgets) attacks.
W^X just addresses different problems.
PIE and RANDEXEC are the real opponents to those attacks
and it's a bit bad that they are not mentioned at all in the paper.
