Locked in heated rivalry with researcher, Microsoft fixes 0-day they disclosed

Nightmare Eclipse disclosed multiple Windows vulnerabilities — including MiniPlasma (a regression tied to CVE-2020-17103), a BitLocker bypass called YellowKey, local escalation flaws (RedSun, BlueHammer), and published exploit code targeting Windows Defender — some of which remain unpatched or only mitigated manually; two were confirmed as zero-days in Microsoft’s recent patch batch.
