Today’s Microsoft security patches include one for a potential remote exploit in… Wordpad?

What next? Are they going to find a plain-text hole in Notepad? Discover you can crash your system by dividing by 0.0000000000001 in Calculator? I know, looking at a malicious font in Character Map is going to be the next big virus vector.
