new RealVNC 4.1 vulnerability - is 4.0 really not affected?

This question pertains to the new RealVNC vulnerability:

I have some clients running RealVNC 4.0.0.
Sources imply that PROBABLY this version is not affected.
(for example: "Note: Version 4.0 is reportedly not affected.).

Can anyone verify that Version 4.0.x is DEFINITELY not affected?

I need to be sure, for obvious reasons.

Thank you!

    You should really check this with the authors (you can submit a support request only if you are not using the free version):

    However, the last item you linked to links to this page:

    Where the guy who discovered the flaw states he has tested this on version 4.0:

     " Then I downloaded RealVNC 4.0 and installed it on another fresh test machine. Same thing as Tight and Ultra - I get disconnected right away. "

    So it would appear he has been unable to re-create the issue on 4.0.
