Microsoft Windows 8.1 and Windows RT 8.1, Windows Server 2012 R2, Windows 10 Gold, 1511, 1607, and 1703, and Windows Server 2016 allow an attacker to set variables that are either read-only or require authentication when Windows fails to enforce case sensitivity for certain variable checks, aka "Windows Security Feature Bypass Vulnerability".

## What to do

- Check your stack: if you ship or depend on Microsoft Corporation Microsoft Windows, no fixed version is listed yet; follow the vendor advisory per the references below.
