How to stop perl service

how to stop perl service on AIX? how to find if per service runing?

perl is not a service. Can you provide more details of what you are trying to accomplish?

It is because IBM announced a vulnerability for perl: AIX Perl buffer overflow vulnerability

And IBM suggests:

VI. WORKAROUNDS

If you are running perl network services there are no known
workarounds.  If the perl services are not needed and are running,
shut them down.

So, I want to know how to shutdown perl.

perl is not running and is not a service. The advisory suggests a work around if you have network programs that are written in perl.

Thank you.
