Summary

This update resolves vulnerabilities in the Microsoft .NET Framework. The vulnerabilities could allow remote code execution if a user either visits a specially crafted website or opens a specially crafted document. This update addresses the vulnerabilities by correcting how the Windows font library handles embedded fonts. To learn more about this vulnerability, see Microsoft Security Bulletin MS16-120.

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.
