crond

[Philipp Schulte <p.schulte@matrix.uni-duisburg.de>]

Hello,
I have read about the recently discovered cron-vulnerabilty but I am a
little bit confused about the versions.
The advisory talks about 3.0pl1-57.3 and I don't know what the "pl" is
supposed to mean.
I am responsible for some non-Debian-systems and rpm reports this to
be installed:

Name        : vixie-cron                
Version     : 3.0.1                     
Release     : 40.1                      

Straightforward question: Is this version vulnerable? What does the
"pl" in the Debian-version mean?

Regards,
Phil
