Update FAQ

Why is security update 3153171 in this bulletin also denoted in MS16-061?
Security update 3153171 is also denoted in MS16-061 for supported releases of Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2, 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

Windows Kernel Elevation of Privilege Vulnerability - CVE-2016-0180

An elevation of privilege vulnerability exists in Microsoft Windows when the Windows kernel fails to properly handle parsing of certain symbolic links. An attacker who successfully exploited this vulnerability could potentially access privileged registry keys and thereby elevate permissions. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system. The update addresses this vulnerability by correcting how the Windows kernel parses symbolic links.
