Yet another reason to drop Internet Explorer and Outlook as your browser and e-mail clients: Microsoft has announced a serious vulnerability in the way it handles the most popular digital picture format. As stated in the previously linked, story from The Register, the hole “potentially allows an attacker to craft a special JPEG file that would take control of a victim’s machine when the user views it through Internet Explorer, Outlook, Word, and other programs. The poisoned picture could be displayed on a website, sent in email, or circulated on a P2P network.”
