Description of the Security and Quality Rollup for the .NET Framework 4.6, 4.6.1, 4.6.2, and 4.7 for Windows Server 2012: September 12, 2017

View products that this article applies to.

Summary

This security update resolves a vulnerability in the Microsoft .NET Framework that could allow remote code execution when Microsoft .NET Framework processes untrusted input. An attacker who successfully exploits this vulnerability in software by using the .NET Framework could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts that have full user rights. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate by using administrative user rights.To exploit the vulnerability, an attacker must first convince the user to open a malicious document or application.This security update addresses the vulnerability by correcting how the .NET Framework validates untrusted input. To learn more about this vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2017-8759.Important

• All updates for .NET Framework 4.6, 4.6.1, 4.6.2, and 4.7 require the d3dcompiler_47.dll update to be installed. We recommend that you install the included d3dcompiler_47.dll update before you apply this update. For more information about the d3dcompiler_47.dll update, see KB 4019990.
• If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see Add language packs to Windows.

Quality and reliability fixes

Networking

• A fix that is included in the May Monthly Security and Quality Rollup is being changed to improve the performance of network latency about Active Directory lookups for the enhanced key usage (EKU) object identifiers (OIDs) function that is used in TLS (Transport Layer Security) and SSL (Secure Sockets Layer) certificates.
  WPF

• Under certain circumstances, Windows Presentation Framework (WPF) applications (particularly Visual Studio) are observed to consume disproportionate amount of CPU cycles in relation to their actual workload. Frequently, these applications eventually crash. This problem is seen in WPF applications that are left running in a locked logon session, or that are left running in a disconnected Terminal Services session.
  CLR

• Under certain circumstances, the JIT compiler can perform an incorrect common subexpression elimination (CSE) optimization that causes an incorrect value to be computed.

• For certain XslCompiledTransform objects, the JIT compiler can perform an incorrect tail call optimization.

• When you run certain large server workloads, the JIT compiler can cause an access violation and early termination of the common language runtime (CLR).
  Winforms

• If Windows Forms controls are anchored to the right edge (a nondefault anchor style value) in a PerMonitor DPI-aware application, anchoring distance is scaled incorrectly on each scaling pass. You may observe that controls are moving toward the right edge of the window on each scaling pass and eventually disappear, or that controls are stretched incorrectly.
  .NET Framework

• Applications that run on the .NET Framework do not respect the settings that are specified in the registry for AppContext switches. Regardless of the registry option setting for an AppContext flag, the application behaves as if the specified value is set to “false.”

Known issues in this update

• After you install the September 12, 2017, .NET Security and Quality Rollups that apply to the .NET Framework 4.6, 4.6.1, 4.6.2, and 4.7, you experience rendering issues in Windows Presentation Foundation (WPF) applications that use WPF types in a Windows service. For more information, see KB 4043601.

Additional information about this security update

For more information about this security update as it relates to Windows Server 2012, see the following article in the Microsoft Knowledge Base:4041084 Security and Quality Rollup for the .NET Framework 3.5, 4.5.2, 4.6, 4.6.1, 4.6.2 and 4.7 updates for Windows Server 2012: September 12, 2017

How to obtain and install the update

Method 1: Windows Update
