No, it's still valid advice.

Hello,

I have recently read on some news provider that Microsoft found a
certian security hole in Word, which they had not yet patched and thus
recomended that people do not use Word as the default Outlook editor
for the time being.

I suppose the message could be bogus or outdated, I have only caught a
glympse of it. I cannot find any other articles saying exactly the same
thing on the internet (or the same article for that matter) and so I
turn to you.

Has there been any such statement by Microsoft lately? If so, does it
affect MS Office 2003 SP2 and it's Outlook?

Thank you in advance for your time.
