I'm not sure that can fix that. Unless they add canaries to the stack
and include other OpenBSD style W^X type checks. I mean, it's the same
problem any OS that uses stacks faces. It's just that we now begin to
see how things are laid out in IOS and gain information about its
routines, how it works, and how to bypass watchdogs and such.

Cisco just has to be more careful with vulnerabilities now since they
can be exploited better :)

Cheers,
