Or, VMware ESXi vulnerability VMSA-2017-0006 remediation planning and execution

Descriptions: On Mar 28th 2017 US-CERT notified it’s users about this vulnerability with VMware ESXi hosts. The remediation of this vulnerability is to update the ESXi hosts with the patch recommended by VMware. In my case the recommended patch was ESXi600-201703003.zip as my VMware ESXi servers are running on version 6.0 U2.

Scenario: As I am using ESXi Server version 6.0 U2, the recommended patches details are as below as per the reported vulnerability security advisory reference KB.

Use this file to update the patches on all affected VMware ESXi servers. You can use either manual method of installing this patch on all affected ESXi servers or you can use the easiest method of doing it by using VMware vSphere update manager.

I am a lazy administrator so don’t expect me to do this patching activity manually. Yes, I used the easiest method of doing it by using Update manager.

I have posted all the steps in my another article How to use Update Manager for patch installation on ESXi servers? . 

You can refer this article if you want to use Update manager for installing these updates on your ESXi hosts.
