Listener Security !!

Hi All !!

   Today I came across a typical Hole in Listener Security. If you have lsnrctl utility (or Database installation) at one Box, then you can stop the listener on another Box. Just change the parameter file (listener.ora) to have hostname of another
(may be production server) box. Now goto lsnrctl and fire stop
command. you would notice that the local listener is running but the remote listener is down.......

        This is more serious issue on platforms like Unix and VMS where you can control listener (locally) only if you are a member of DBA group. This means that Listener doesn't have any cross OS check in it....

        Is this a known issue/bug. Any-ideas, any patches? Oracle Corp guys, what you say?

        Waiting for you views......
