The Security Mentor

If you have Real Player installed on your machine then a bad guy can put together a .WAV or .SMIL file which will take over your computer if you open it. According to the Real Networks security announcement, Mac and Linux systems are affected too. Follow that link to get the updated versions with the security hole fixed.

The good news is that as far as we know the bad guys aren't using this security hole yet. The bad news is that Internet Explorer can open at least one of those file types automatically when you simply visit a web page.

Update right away if you frequent multimedia web sites, otherwise you can schedule the update for whenever it's convenient.
