Microsoft Fixes Zero-Day, Four Other Flaws in IE
Summary: Microsoft released emergency update MS12-063 for Internet Explorer, fixing at least five vulnerabilities including a zero-day flaw attackers had been using to break into vulnerable systems. The vulnerability resides in IE 7, 8, and 9 on nearly all supported versions of Windows, apart from certain installations of Windows Server 2008 and Windows Server 2012, and Microsoft separately updated Adobe Flash Player libraries within IE 10 on Windows 8 and Windows Server 2012.
Why it matters: The zero-day was already being used in attacks before the patch shipped, and Microsoft credited an anonymous researcher working with HP's Tipping Point Zero Day Initiative for the discovery, with reporting suggesting ZDI may have known for a month to well over a year before the flaw became public.
