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

Synopsis

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

Description

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).

Solution

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.
