"anyone who received what appeared to be a Flash update from the website should change all of their passwords on their computer"
I've just checked via $eselect news read new, and I don't have any exhortations to update my Flash thingie. Sounds like a good excuse to reset all Windows using folk's passwords. I can probably intimate iStuff owners as well - hillarious. Damn, I'm so smug - it hurts.
I wonder if I'm still the only root user on my computers ...
