Microsoft Security Advisory 4053440

Securely opening Microsoft Office documents that contain Dynamic Data Exchange (DDE) fields
The title says it all.
There is a vulnerability in MS Office and it is being actively exploited. Though you can edit the registry to block attacks as a temporary fix I don’t recommend it. Why? Because I actually read what Microsoft had to say, “The attacker would have to convince the user to disable Protected Mode and click through one or more additional prompts.” That means you have to download a malicious document, open it, and accept the “Enable editing” prompt. I don’t believe y’all are that stupid. Microsoft will fix this by and by.
