[1]Beginning with the October 2016 release, Microsoft is changing the update servicing model for Windows 7, Windows Server 2008 R2, Windows 8.1, Windows Server 2012, and Windows Server 2012 R2. For more information, please see this Microsoft TechNet article.

[2]This update is only available via Windows Update.

[3]Windows 10 and Windows Server 2016 updates are cumulative. The monthly security release includes all security fixes for vulnerabilities that affect Windows 10, in addition to non-security updates. The updates are available via the Microsoft Update Catalog. Please note that effective December 13, 2016, Windows 10 and Windows Server 2016 details for the Cumulative Updates will be documented in Release Notes. Please refer to the Release Notes for OS Build numbers, Known Issues, and affected file list information.

*The Updates Replaced column shows only the latest update in any chain of superseded updates. For a comprehensive list of updates replaced, go to the Microsoft Update Catalog, search for the update KB number, and then view update details (updates replaced information is provided on the PackageDetails tab).

Update FAQ

Why is security update 4012497 in this bulletin also denoted in MS17-013?
Security update 4012497 is also denoted in MS17-013 for supported releases of Windows Vista and Windows Server 2008 due to the way fixes for vulnerabilities affecting particular products are consolidated. Because bulletins are broken out by the vulnerabilities being addressed, not by the update package being released, it is possible for separate bulletins, each addressing distinctly different vulnerabilities, to list the same update package as the vehicle for providing their respective fixes. This is frequently the case with cumulative updates for products, such as Internet Explorer or Silverlight, where singular security updates address different security vulnerabilities in separate bulletins.

Note Users do not need to install identical security updates that ship with multiple bulletins more than once.

Vulnerability Information

Multiple Win32k Elevation of Privilege Vulnerabilities

Multiple elevation of privilege vulnerabilities exist in Windows when the Windows kernel-mode driver fails to properly handle objects in memory. An attacker who successfully exploited these vulnerabilities could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

To exploit these vulnerabilities, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerabilities and take control of an affected system.

The update addresses these vulnerabilities by correcting how the Windows kernel-mode driver handles objects in memory.

The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:
