VMware vCenter Server 5.5.x < 5.5U3g / 6.0.x < 6.0U3d / 6.5.x < 6.5U1e Hypervisor-Assisted Guest Remediation (VMSA-2018-0004) (Spectre)

medium Nessus Plugin ID 105784
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote VMware ESXi host is missing a security patch which enables hardware support for branch target mitigation.


The version of VMware vCenter Server installed on the remote host is 5.5.x prior to 5.5U3g, 6.0.x prior to 6.0U3d, or 6.5.x prior to 6.5U1e. It is, therefore, missing security updates that add hypervisor-assisted guest remediation for a speculative execution vulnerability (CVE-2017-5715).


Upgrade to VMware vCenter Server version 5.5.U3g (5.5.0 build-7460778) / 6.0U3d (6.0.0 build-7464194) / 6.5U1e (6.5.0 build-7515524) or later.
