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

[2]Windows 10 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.

[3]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.

Note The vulnerabilities discussed in this bulletin affect Windows Server 2016 Technical Preview 5. To be protected from the vulnerabilities, Microsoft recommends that customers running this operating system apply the current update, which is available from Windows Update.

*The Updates Replaced column shows only the latest update in any chain of superseded updates.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 Package Details tab).

Multiple Win32k Elevation of Privilege Vulnerabilities

Elevation of privilege vulnerabilities exist 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:

Windows Transaction Manager Elevation of Privilege Vulnerability

An elevation of privilege vulnerability exists when the Windows Transaction Manager improperly handles objects in memory. In a local attack scenario, an attacker could exploit this vulnerability by running a specially crafted application to take control over the affected system. An attacker who successfully exploited this vulnerability could run processes in an elevated context. 

The update addresses the vulnerability by correcting how the Transaction Manager handles objects in memory.
