MS11-099 is a Microsoft security bulletin from December 2011, rated Important, that provides a cumulative security update for Internet Explorer (KB2618444). It addresses three privately reported vulnerabilities, the most severe of which could allow remote code execution if a user opens a legitimate HTML file located in the same directory as a specially crafted DLL file. The bulletin was revised on December 13, 2011, to correct severity ratings in the Affected Software table. This update is part of Microsoft's monthly security release cycle and is relevant for users maintaining older Internet Explorer versions on Windows systems.
