.NET Framework December 2018 Security and Quality Rollup

Tara Overfield


Today, we are releasing the December 2018 Security and Quality Rollup.


CVE-2018-8540 – Windows Remote Code Execution Vulnerability

This security update resolves a vulnerability in Microsoft .NET Framework that could allow remote code execution when Microsoft .NET Framework doesn’t validate input correctly. The attacker who successfully exploits this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts that use full user rights. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who are granted administrative user rights.

Getting the Update

The Security and Quality Rollup is available via Windows Update, Windows Server Update Services, Microsoft Update Catalog, and Docker.

Microsoft Update Catalog

You can get the update via the Microsoft Update Catalog. For Windows 10, .NET Framework updates are part of the Windows 10 Monthly Rollup.
