MySpace was on top of the situation, sort of --it's old news now. Here's their response

They had to negotiate with Apple to do something about it because it required Apple to update Quicktime, to not give hackers the ability to use it that way. Anyway, this happened in December so that particular hack is old news now and doesn't work any more--which is not to say that Quicktime has been modified yet to ensure that new ones won't come through the same hole.
