*The Updates Replaced column shows only the latest update in a chain of superseded updates.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

Does this update contain any additional security-related changes to functionality? 
In addition to the changes that are listed for the vulnerabilities described in this bulletin, this update includes defense-in-depth updates to help improve security-related features.

I am running Office 2010, which is listed as affected software. Why am I not being offered the update? 
The update is not applicable to Office 2010 on Windows Vista and later versions of Windows because the vulnerable code is not present.

I am being offered this update for software that is not specifically indicated as being affected in the Affected Software and Vulnerability Severity Ratings table. Why am I being offered this update? 
When updates address vulnerable code that exists in a component that is shared between multiple Microsoft Office products or shared between multiple versions of the same Microsoft Office product, the update is considered to be applicable to all supported products and versions that contain the vulnerable component.

For example, when an update applies to Microsoft Office 2007 products, only Microsoft Office 2007 may be specifically listed in the Affected Software table. However, the update could apply to Microsoft Word 2007, Microsoft Excel 2007, Microsoft Visio 2007, Microsoft Compatibility Pack, Microsoft Excel Viewer, or any other Microsoft Office 2007 product that is not specifically listed in the Affected Software table. Furthermore, when an update applies to Microsoft Office 2010 products, only Microsoft Office 2010 may be specifically listed in the Affected Software table. However, the update could apply to Microsoft Word 2010, Microsoft Excel 2010, Microsoft Visio 2010, Microsoft Visio Viewer, or any other Microsoft Office 2010 product that is not specifically listed in the Affected Software table.

For more information on this behavior and recommended actions, see Microsoft Knowledge Base Article 830335. For a list of Microsoft Office products an update may apply to, refer to the Microsoft Knowledge Base Article associated with the specific update.

Are there any prerequisites for any of the updates offered in this bulletin for affected editions of Microsoft Lync 2013 (Skype for Business)? 
Yes. Customers running affected editions of Microsoft Lync 2013 (Skype for Business) must first install the 2965218 update for Office 2013 released in April, 2015, and then the 3039779 security update released in May, 2015. For more information about these two prerequisite updates, see:

Are there any related non-security updates that customers should install along with the Microsoft Live Meeting Console security update? 
Yes, in addition to releasing a security update for Microsoft Live Meeting Console, Microsoft has released the following non-security updates for the OCS Conferencing Addin for Outlook. Where applicable, Microsoft recommends that customers install these updates to keep their systems up-to-date:

  • OCS Conferencing Addin for Outlook (32-bit) (3144431)
  • OCS Conferencing Addin for Outlook (64-bit) (3144431)

See Microsoft Knowledge Base Article 3144431 for more information.

Why is the Lync 2010 Attendee (user level install) update only available from the Microsoft Download Center? 
Microsoft is releasing the update for Lync 2010 Attendee (user level install) to the Microsoft Download Center only. Because the user level installation of Lync 2010 Attendee is handled through a Lync session, distribution methods such as automatic updating are not appropriate for this type of installation scenario.

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 the 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 the 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 the vulnerabilities by correcting how the Windows kernel-mode driver handles objects in memory.

Graphics Memory Corruption Vulnerability – CVE-2016-0145

A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited the vulnerability could install programs; view, change, or delete data; or create new accounts with full user rights.

There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage that contains embedded fonts. The security update addresses the vulnerability by correcting how the Windows font library handles embedded fonts.
