Microsoft Security Bulletin MS17-011 - Critical

Security Update for Microsoft Uniscribe (4013076)

Published: March 14, 2017

Version: 1.0

Executive Summary

This security update resolves vulnerabilities in Windows Uniscribe. The most severe of these vulnerabilities could allow remote code execution if a user visits a specially crafted website or opens a specially crafted document. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

This security update is rated Critical for all supported editions of Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8.1, Windows Server 2012, Windows RT 8.1, Windows Server 2012 R2, Windows 10, Windows 10 Version 1511, Windows 10 Version 1607, and Windows Server 2016. For more information, see the Affected Software and Vulnerability Severity Ratings section.

The security update addresses these vulnerabilities by correcting how Windows Uniscribe handles objects in memory. For more information about these vulnerabilities, see the Vulnerability Information section.

For more information about this update, see Microsoft Knowledge Base Article 4013076.

[1]Beginning with the October 2016 release, Microsoft has changed 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*The Updates Replaced column shows only the latest update in any chain of superseded updates.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 Package Details tab).

Update FAQ

Why is security update 4012583 in this bulletin also denoted in MS17-013?
Security update 4012583 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 Windows Uniscribe Remote Code Execution Vulnerabilities

Multiple remote code execution vulnerabilities exist in Windows due to the way Windows Uniscribe handles objects in memory. An attacker who successfully exploited these vulnerabilities could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

There are multiple ways an attacker could exploit these vulnerabilities:

  • In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit these vulnerabilities and then convince a user to view the website. An attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to click a link in an email or instant message that takes users to the attacker's website, or by opening an attachment sent through email.
  • In a file sharing attack scenario, an attacker could provide a specially crafted document file designed to exploit these vulnerabilities and then convince a user to open the document file.

The security update addresses these vulnerabilities by correcting how Windows Uniscribe handles objects in memory.

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

Vulnerability title CVE number Publicly disclosed Exploited
Windows Uniscribe Remote Code Execution Vulnerability CVE-2017-0072 No No
Windows Uniscribe Remote Code Execution Vulnerability CVE-2017-0083 No No
Windows Uniscribe Remote Code Execution Vulnerability CVE-2017-0084 No No
Windows Uniscribe Remote Code Execution Vulnerability CVE-2017-0086 No No

Windows Uniscribe Remote Code Execution Vulnerability CVE-2017-0088 No No
Windows Uniscribe Remote Code Execution Vulnerability CVE-2017-0089 No No
Windows Uniscribe Remote Code Execution Vulnerability CVE-2017-0090 No No

Mitigating Factors

Microsoft has not identified any mitigating factor for these vulnerabilities.

Workarounds

Microsoft has not identified any workarounds for these vulnerabilities.

Multiple Uniscribe Information Disclosure Vulnerabilities

Multiple information disclosure vulnerabilities exist when Windows Uniscribe improperly discloses the contents of its memory. An attacker who successfully exploited these vulnerabilities could obtain information to further compromise the user’s system.

There are multiple ways an attacker could exploit the vulnerabilities, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage.

The update addresses these vulnerabilities by correcting how the Windows Uniscribe handles objects in memory.

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