    Hi,
    
    The "ruid" idea and prevent exec/fork of suid programs, is a nice idea but
    is really security through obscurity.
    
    If a hacker knows this patch is in place, he just replaces the shellcode
    so instead of doing:
    
    syscall exec /bin/sh
    
    it does
    
    syscall chmod 666 /etc/passwd
    
    or any other exciting piece of code you care to run. You need not launch a
    separate process to run it.
    
    Cheers
    Chris
