New! Plugin Severity Now Using CVSS v3

Synopsis

The remote VMware ESXi host is missing a security patch and is affected by multiple vulnerabilities.

Description

The remote VMware ESXi host is version 6.0, 6.5 or 6.7 and is missing a security patch. 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 (MLPDS) (CVE-2018-12127)
 - Microarchitectural Fill Buffer Data Sampling (MFBDS) (CVE-2018-12130)
 - Microarchitectural Data Sampling Uncacheable Memory (MDSUM) (CVE-2019-11091)

Note virtual machines must be configured with the 3D-acceleration enabled. VMware ESXi defaults to this feature not being enabled.

Solution

Apply the appropriate patch as referenced in the vendor advisory.
