Microsoft Security Bulletin Advance Notification for December 2011

No worries

Although I don't know the specifics, it affects the Windows truetype font engine, and there was mention that opening an infected Word document was enough to allow malicious shell script to run that could give hackers ability to run code in kernel mode.

 

So with the Fixit applied, one loses custom handwriting fonts in IE?
Not the end of the world.

 

Yeah, I'm not sure if that's all that breaks?? Hopefully that's it.

BTW, there's more here on how the exploit works. Post #86 provides a flow chart on it

 

I just dug out some notes on this and read here that "applications that have functionality that relies on the T2embed.dll file, such as applications that generate PDF files, may not work as expected. For example, Microsoft Office software will be unable to generate PDF files".

 

Okay, so it has more impact than just font rendering. Oh well, maybe better to leave the Fixit out, but as mrBrian pointed out, it would depend on the person's needs.
