The Electronic Frontier Foundation has found that 37,000 certificates have been given out to unauthorized names. That means you could be subjected to "man in the middle" attacks, where you go to a website, you think you're at that website - everything looks the same, but you're not really at that website. You're at a website that looks like the one you want to go to, but it's a fake site designed to monitor your actions and/or get your personal information.
