And the good news is: a patch for the Word vulnerability appears to be in the pipeline. It's critical that everybody still using Office 2003 apply this update. Why? Because it will only take days for the patch to be reversed and for related exploits to be injected into exploit kits. At which point, browsing the web becomes considerably more hazardous for anybody with Office installed. Particularly if your browser is configured to "open" RTF files.
So prepare to patch next Tuesday! Do it.
