FortiClientVPN 7.4.3 CWE-427

Hi @Shuhei ,

As per the advisory here - https://fortiguard.fortinet.com/psirt/FG-IR-25-685 - the resolved versions are 7.4.4 and upwards. 

It is my understanding there will always be a free version of FortiClient going forward. There simply hasn't been any need to release a new version yet. The paid version updates included new features/fixes for paid versions.
