Redmond said that it released the software, known as a "Fix It," as an emergency measure to protect customers after learning about "extremely limited, targeted attacks" that made use of the newly discovered bug. Microsoft said the attacks took advantage of an undiscovered flaw, or "zero day" vulnerability in industry parlance.
Internet Explorer users should either immediately install the Fix It or stop using the browser until Microsoft can put out an update, which will be automatically installed through its Windows Update program. The Fix It can be installed by clicking on a link this page on Microsoft's support site here.
