Adobe just patched a critical bug in its incredibly popular Macromedia Flash Player. Exploitation of the flaw could leave your PC completely compromised via memory corruption, according to security researcher Fortinet. When you visit a Web site that contains a Flash movie (an .swf file), Flash Player automatically loads on your PC and plays the file.
All you'd have to do to get hit is visit a booby-trapped site. Once you were there, the file would play with no additional click from you. Versions 8.0.24 and earlier are at risk, according to Fortinet. Don't put off getting Adobe's updated release, version 9.0.16.
