How to find installed NagiosVer. 3.1.0 is DYI or Student et

[Urgent]
Hello,
I need to upgrade Nagios Core version from Ver. 3.1.0 to version 3.4.4 (because in current 3.1.0 version we are facing issue "Nagios3 history.cgi Buffer Overflow Vulnerability" is detected). So I need to upgrade.

Question : What is the commandline (my system is CentOS 5.1) to find out whether existing old Nagios Core version Ver. 3.1.0 is DYI or Student / Proffesional / Business Type?
Reference : http://www.nagios.org/download/core

Because I have to download 3.4.4 version, so I am confused which one to install and upgrade (DYI or Student / Proffesional / Business Type)? There is no previous history to identify the existing version type in my server.

This is little urgent, so please help.
Waiting for your response soon.
Thank you in advance,
~Tapan

Student / Proffesional / Business Type

If you are talking about the core VM's, these are purchase options, if you did not purchase a core VM within the last 6 months or so that they have been available then you are just running standard Core.
