Thanks so very much waking and sunrisecc for the links. This is quite interesting, and intriguing. To patch or not to patch, that is the question?

I'm doing a bit of research on my own with this one. As long as you're not experiencing any problems, I wouldn't worry about it just yet.
They (Microsoft) may or may not let you know where the problem lies. Sometimes, it's better they don't let "the cat out of the bag" as it were. Even after they find out what they need to know. Keeps the hounds (hackers) at bay for a while longer.
