Microsoft hasn't notified us of a problem (which I
would expect them to do as a courtesy if our code had
the same problem (we do this for them), so my guess
is we're not vulnerable.

Until we know the exact details of the exploit however,
we're still stumbling around in the dark until we know
exactly what to look for.
