QuickTime Security Vulnerabilty

This seems like a pretty worrisome security alert for QuickTime. A malicious QuickTime file could take over your system (Mac or PC). You could come across one of these movies on a webpage or in an email. The good news: no malicious QuickTime movies have been found in the wild. The bad news: code has been released to the public to exploit this flaw. Nothing to panic about yet. Let it be a reminder not to open attachments unless you know who it comes from and the attachment is explained in the email.
