Looks like the folks on the MSRC blog just posted the August security bulleting webcast and customer Q&A.  To quote their site:

It is apparent that there is still a bit of confusion around the Active Template Library (ATL) issue and how current updates relate to work we have already done to provide mitigations, protections and guidance to customers. To try and provide some clarity:

• Security Advisory 972890: This advisory was released in response to active attacks against the Microsoft Video ActiveX Control in order to provide guidance and mitigations (including a Microsoft Fix it solution) to customers while we worked towards an update for the underlying issue.
• MS09-032 – Cumulative Update of ActiveX Kill Bits (973346): This bulletin provided an official kill bit update to replace the Microsoft Fix it solution provided by Security Advisory 972890. The update addresses additional kill bits and is also available through Microsoft update technologies such as Windows Update, Microsoft Update, and Windows Software Update Services (WSUS). This kill bit blocked the ability to instantiate the Microsoft Video ActiveX Control in Internet Explorer to mitigate against known attacks.
• MS09-034 – Cumulative Security Update for Internet Explorer (972260): This bulletin provided a defense-in-depth update that helps mitigate known attack vectors within Internet Explorer. To be clear, Internet Explorer is not vulnerable to these attacks but the vulnerable components can be reached through Internet Explorer. Installing this update mitigates that threat.
• MS09-035 – Vulnerabilities in Visual Studio Active Template Library Could Allow Remote Code Execution (969706): This update is specifically geared towards developers of components and controls who use ATL. The update addresses the underlying issue in our Visual Studio development tools. Developers who use ATL should install this update and recompile their components and controls following the guidance in this MSDN article.
• MS09-037 – Vulnerabilities in Microsoft Active Template Library (ATL) Could Allow Remote Code Execution (973908): This bulletin provides updates for vulnerable components and controls that shipped with Windows products. These are Microsoft components and controls were built using ATL. Among the updates in this bulletin is a binary level update that addresses the vulnerability in the Microsoft Video ActiveX Control that has seen some active attacks. So we previously released a kill bit update to provide immediate protection for customers and are addressing the underlying vulnerability with this update.
• Security Advisory 973882: This advisory provides information on our ongoing investigation in to the ATL issue and serves as a single source for all related information.

To be even clearer, not every ActiveX control is vulnerable and we have an ongoing investigation into this issue. We will continue to provide updates via Security Advisory 973882 and Security Bulletins as necessary.

Of course this is not the only issue we addressed this month and customers had quite a few questions during the webcast that we provided answers and guidance for.
