VMware vSphere Spectre Vulnerability - Patches available since November

With the info released about the Meltdown and Spectre vulnerabilities, in case you are running VMware vSphere, you may already have applied the patches mentioned in VMSA-2018-0002, maybe even beat them on AWS (especially if you are on vSphere 6.0). 

For example the patch for ESXi 6.0, ESXi600-201711101-SG, was silently released in November last year, on November 09, 2017, as can be seen from Update Manager below or their KB 2151132.

vSphere 6.5 got the patch ESXi650-201712101-SG somewhat later, per their KB 2151099, on December 19, 2017. ESXi 5.5 got the incomplete patch ESXi550-201709101-SG also early on September 14, 2017, per their KB 2150876.

As a small note, for example ESXi650-201712101-SG, being a security release only, is included in the ESXi600-201711401-BG release as well which is a general bulletin (a general bulletin contains both the new security and bug fixes on top of the last version of the VIBs, see KB 2041654 for explanation). So installing ESXi600-201711401-BG in tandem with ESXi650-201712101-SG will make the SG appear as "obsoleted by host.
