Zero-Day Threat - Internet Explorer Weakness 9/17/12 - back door Trojan - Poison Ivy

How are others responding to this NEW threat? Is Sophos patching with a Microsoft Enhanced Mitigation Experience Toolkit 3.0? (Reported to be a viable solution to protecting from the threat according to Yunsun Wee of Microsoft)

Looks like I jumped the gun. Sophos has responded. They are suggesting the Microsoft solution:

Solution	http://technet.microsoft.com/en-us/security/advisory/2757760
Vendor description	Microsoft is investigating public reports of a vulnerability in Internet Explorer 6, Internet Explorer 7, Internet Explorer 8, and Internet Explorer 9. Internet Explorer 10 is not affected. Microsoft is aware of targeted attacks that attempt to exploit this vulnerability. A remote code execution vulnerability exists in the way that Internet Explorer accesses an object that has been deleted or has not been properly allocated. The vulnerability may corrupt memory in a way that could allow an attacker to execute arbitrary code in the context of the current user within Internet Explorer. An attacker could host a specially crafted website that is designed to exploit this vulnerability through Internet Explorer and then convince a user to view the website. On completion of this investigation, Microsoft will take the appropriate action to protect our customers, which may include providing a solution through our monthly security update release process, or an out-of-cycle security update, depending on customer needs.
SophosLabs comments	This security update resolves a publicly reported vulnerability. SophosLabs urgently requests that customers perform the MS interim workaround solution mentioned.
