The discussion about the various techniques for buffer overflow
prevention is very interesting, but if the target is to prevent the
security threats caused by buffer overflows, then one should look for
an operating system base solution, since it is an OS issue to enforce
the security. Solutions based on the control of system calls execution
like systrace (http://www.citi.umich.edu/u/provos/systrace/) or
remus (http://remus.sourceforge.net/) are just two possible examples of
such approach.
