Microsoft Security Bulletin MS16-074 - Important

Security Update for Microsoft Graphics Component (3164036)

Published: June 14, 2016 | Updated: June 15, 2016

Version: 1.1

This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow elevation of privilege if a user opens a specially crafted application.

This security update is rated Important for all supported releases of Microsoft Windows. For more information, see the Affected Software and Vulnerability Severity Ratings section.

The security update addresses the vulnerabilities by correcting how:

  • The Windows Graphics Component (GDI32.dll) handles objects in memory
  • The Windows kernel-mode driver (Win32k.sys) handles objects in memory and helps to prevent unintended elevation of privilege from user-mode
  • The Adobe Type Manager Font Driver (ATMFD.dll) handles objects in memory

For more information about the vulnerabilities, see the Vulnerability Information section.

For more information about this update, see Microsoft Knowledge Base Article 3164036.

The following software versions or editions are affected. Versions or editions that are not listed are either past their support life cycle or are not affected. To determine the support life cycle for your software version or edition, see Microsoft Support Lifecycle.

The severity ratings indicated for each affected software assume the potential maximum impact of the vulnerability. For information regarding the likelihood, within 30 days of this security bulletin’s release, of the exploitability of the vulnerability in relation to its severity rating and security impact, please see the Exploitability Index in the June bulletin summary.

Windows Graphics Component Information Disclosure Vulnerability – CVE-2016-3216

An information disclosure vulnerability exists when the Windows Graphics Component (GDI32.dll) fails to properly handle objects in memory, allowing an attacker to retrieve information that could lead to an Address Space Layout Randomization (ASLR) bypass. An attacker who successfully exploited this vulnerability could cause an information disclosure to bypass the ASLR security feature that protects users from a broad class of vulnerabilities.

The security feature bypass itself does not allow arbitrary code execution. However, an attacker could use the ASLR bypass vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability, that could take advantage of the ASLR bypass to run arbitrary code.

To exploit this vulnerability, an attacker could convince a use to run a specially crafted application. The security update addresses the vulnerability by correcting how the Windows Graphics Component handles addresses in memory.

Win32k Elevation of Privilege Vulnerability – CVE-2016-3219

An elevation of privilege vulnerability exists when the Windows improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context.

In a local attack scenario, an attacker could exploit this vulnerability by running a specially crafted application to take control of the affected system. The update addresses the vulnerability by correcting how the Windows kernel-mode driver handles objects in memory and by helping to prevent unintended elevation of privilege from user-mode.

ATMFD.dll Elevation of Privilege Vulnerability – CVE-2016-3220

An elevation of privilege vulnerability exists in Adobe Type Manager Font Driver (ATMFD.dll) when it fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code and take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

To exploit the vulnerability, an attacker would first have to log on to a target system and then run a specially crafted application. The security update addresses the vulnerability by correcting how ATMFD.dll handles objects in memory.
