(Not picking on you Mr. Bayer!)

All the discussion I have seen so far about recent virus has focused on
software.  To what extent can hardware be at fault?  Was the one of the
reasons the two processor types were attacked because they would allow
code to be executed in data space?  Is this what happened?  Some other
machines will produce a core dump if you pull this.  What else can be done
in hardware to enhance the security of the UNIX(r) operating system?
