Surprisingly relevant
Lots of jokes on IE going around. It's not cool, it's not Chrome, sure ... but, in various versions, it's still in use. I'm always surprised by the IE 7 and older versions that pop up when I check Google Analytics traffic to my company's website. And hardly outdated, this has been the case of the last few places I've worked. Curious, Tim, does Dark Reading/IW still get lots of traffic from older versions of IE?

Re: Surprisingly relevant
There are still lots of older versions of IE out there, and they have lots of holes in them. :)  This particular vuln goes up to IE 11, though, so even more current versions may be at risk.

Be aware the APT behind the attacks
The impact is very serious considering the diffusion of various versions of IE affected by 0-day. Anyway, I invite you to carefully consider that as highlighted by experts at FireEye, we are facing with a very prolific APT that had access to different zero-day exploits in the last months.

EMET
Yet another reason to download and run Microsoft's free EMET tool, which stops this exploit.

Re: EMET
EMET 4.1 to be specific. Also if you are running Enhanced Protection Mode for versions 10 and 11 for IE this will also help mitigation of this vulnerability. 

Protected mode which is is EPM's predecessor from IE7 has the ability to leverage XSS filter but this only alleviates the stress for Web Vulnerability exploits and not Browser Exploits. The EPM has functionality to protect against memory vulnerabilities leveraged from your browser as well as XSS. For these two reasons Enhanced Protection Mode should be enabled on all machines running IE 10/11.

Re: EMET
Agreed, Kelly.  I installed EMET in <5 mins. and the default settings protect IE.  This is an amazing tool, I;m going to role it out to the 2,000 PCs we manage.

Re: EMET
And then there's my personal favorite and long-practiced strategy: don't use IE.

Re: EMET
I couldn't help but think that the sriousness of this vulnerability and the existing threat landscape would prompt Microsoft to patch the flaw for XP as well. Sure enough, there is an out of band patch for all versions including XP.

Another reason not to grant Admin rights to End User.
So, this exploit does not escalate to System privileges? I don't see this being much of a concern if successfully executed from a Standard account. If for some problematic reason with client software they MUST be an Administrator, their Internet Explorer could always be launched using DropMyRights.

VGX.dll
I have also seen that a vast majority of instances where this vulnerability is prevalent deals with VGX.dll. This is based on a deprecated markup language and most likely is should no longer be used at your enterprise unless you have legacy systems running. 

The resolution for this involves unregistering of the DLL which can be accomplished easily by using the command-line. Also, make sure you do this is a test environment first. It would be very detrimental if your enteprise did run an application that leverage VGX.dll.
