Microsoft Fixes Zero-Day, Four Other Flaws in IEMicrosoft has released an emergency update for Internet Explorer that fixes at least five vulnerabilities in the default Web browser on Windows, including a zero-day flaw that miscreants have been using to break into vulnerable systems.
The patch, MS12-063, is available through Windows Update or via Automatic Update. If you installed the stopgap "fix it" tool that Microsoft released earlier this week to blunt the threat from the zero-day bug, you need not reverse or remove that fix it before applying this update. 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.
