From the article... "the biggest blip on the security radar was the realization by the security community that an Internet Explorer problem first identified six months ago was a lot worse than it appeared.
The realization caused Secunia to issue a rare 'Extremely Critical' advisory. Once thought just to be a DoS vulnerability, it turns out that it also allows execution of arbitrary code."
We talked about this on the show on Sunday. If you haven't taken it seriously yet, it's time to.
