Summary

This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application.



To learn more about the vulnerability, see Microsoft Security Bulletin MS16-018.

More Information

This security update also fixes the following nonsecurity-related issues:

  • Fixes a deadlock in win32k.sys that can occur when multiple threads concurrently run GDI operations where font fallback is necessary (for example, when you use a character that does not exist in the selected font).

  • On rare occasions, WM_LBUTTONDBLCLK isn't generated the first time user double clicks the ActiveX controls.

  • A rounding error in GDI that occurs on x64-based computers can result in 1-pixel lines that do not render.

  • Some applications have missing headers in SysListView32 controls when they are accessed through Microsoft RemoteApp.


Important

  • All future security and nonsecurity updates for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 require update¬†2919355 to be installed. We recommend that you install update 2919355 on your Windows RT 8.1-based, Windows 8.1-based, or Windows Server 2012 R2-based computer so that you receive future updates.

  • 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.
