Leo and I carefully examine the operation of the recently patched Windows MetaFile vulnerability. I describe exactly how it works in an effort to explain why it doesn't have the feeling of another Microsoft "coding error." It has the feeling of something that Microsoft deliberately designed into Windows. Given the nature of what it is, this would make it a remote code execution "backdoor." We will likely never know if this was the case, but the forensic evidence appears to be quite compelling.

If this is correct (And I'm not saying that it is - just thinking that is too scary), then it means that the WMF exploit was actually a deliberatly coded backdoor in the windows operating system. Surely this is the ultimate proof of why a closed source operating system can not be a safe one. The Windows MetaFile Backdoor? |
