No, unless, there is some bug, and any bugs in any code pretty much calls off 
any talk of security.

Yes Simon, you found a bug, and it has now been fixed.  Can you still use the

Unless you find another bug, then a non-prived user cannot gain privs, unless 
they are granted to that user or process.
