Security Updates

For those who need to prioritize deployment, we recommend focusing on these two Critical updates first:

MS12-071 (Internet Explorer): This bulletin addresses three privately disclosed issues, none of which are currently known to be under active attack. Successful exploitation of these issues could result in code execution with the current user's privileges. As such, we recommend the best practice of running applications with the least privileges possible in order to help mitigate potential risks. These issues do not affect Internet Explorer 10.

MS12-075 (Windows Kernel): This security update addresses three privately reported issues, none of which are currently known to be under active attack. This bulletin affects all supported versions of Microsoft Windows. The most severe issue could result in remote code execution if an attacker is able to lure a user to a website with a maliciously crafted TrueType font file embedded.

Security Update Re-release

In October we released Security Advisory 2749655 that addresses potential compatibility issues due to signature timestamps expiring before they should and noted we would be providing updates as they become available. Today we are providing one such update for MS12-046 (Visual Basic), which is now listed as available in the advisory. We have also released MS12-062 (System Center Configuration Manager 2007) to address an issue in the localization of resource files. Users who have already successfully installed the English versions of this update do not need to take any action.
