Microsoft Security advisory on WMF exploit
I’ve read the security advisory and unfortunately Microsoft doesn’t give any real workarounds. (There have been several announced from other sources.) Unfortunately, Microsoft: 1)urges caution in opening email and links from untrusted sources, and 2) wants you to call them if you’ve been affected by this. (1-866-PCSAFETY) and 3) make sure you have all updates (which currently don’t protect against this vulnerability) and a list of other things that don’t mitigate against this threat. Disappointing.
Correction — I just noticed, they do mention the “unregister” workaround, I missed it when I looked at the document I missed that you have to click on “workarounds” after viewing the “suggested actions” section. After all that time working on the virtual machine I’m probably not as sharp as I could be.
