Summary

This update resolves a vulnerability in Microsoft .NET Framework that could cause denial of service when .NET Framework and .NET core components process XML documents incorrectly. An attacker who has successfully exploited this vulnerability could cause a denial of service against a .NET Framework application. To learn more about this vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2018-0765.Additionally, this update resolves a security feature bypass vulnerability in Windows that could allow an attacker to bypass Device Guard. An attacker who successfully exploits this vulnerability could circumvent a User Mode Code Integrity (UMCI) policy on the computer. To learn more about this vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2018-1039. 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 for Windows 7 SP1 and Windows Server 2008 R2 SP1. Or, see KB 4019478 for Windows Server 2008 SP2.
  • 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 improvements

CLR1|

  • Fixed a floating-point overflow in the thread pool’s hill climbing algorithm.
  • When you observe high CPU usage by ntoskrnl!KiPageFault that originates from BGC (as indicated by theclr!gc_heap::bgc_thread_function), you might want this change so that the GC no longer uses the OS-implementedGetWriteWatchfunction to track BGC heap modifications. That process is very expensive because each of these page faults must take a process-wide lock. This is especially noticeable in the recent versions of the OS. You are probably seeing that most of the CPU is spent in thentoskrnl!ExpWaitForSpinLockExclusiveAndAcquirefunction. This fix makes GC use CLR’s own implementation of theGetWriteWatch* function instead.
