Synopsis
The remote Windows host is missing a microcode update.Description
The remote Windows host is missing a security update. It is, therefore, missing microcode updates to address the following vulnerabilities:- Microarchitectural Store Buffer Data Sampling (MSBDS) (CVE-2018-12126).
- Microarchitectural Load Port Data Sampling (CVE-2018-12127)
- Intel® Running Average Power Limit (RAPL) Interface (CVE-2020-8695)
Note that Nessus did not actually test for these flaws nor checked the target processor architecture but instead, has relied on the version of mcupdate_GenuineIntel.dll to be latest for supported Windows release.
Solution
Microsoft has released security updates for Windows 10, Windows Server 2016 and Server 2019.See Also
