How to find Safari Version Number

In light of the recent spectre and meltdown patches i have been tasked with trying to find out what the version number for the various levels of patches are for each that are available. I am trying to do this via ARD as doing it manually if fairly easy.

So far i am running either of these commands:

mdls -name kMDItemVersion /Applications/Safari.app

When i run that i get the following:

kMDItemVersion = "11.0.2"

I tried running this :

system_profiler -detailLevel full

I get the following:

Safari:

Version: 11.0.2

Obtained from: Apple

Last Modified: 1/10/18, 4:16 PM

Kind: Intel

64-Bit (Intel): Yes

Signed by: Software Signing, Apple Code Signing Certification Authority, Apple Root CA

Location: /Applications/Safari.app

Get Info String: 11.0.2, Copyright © 2003-2017 Apple Inc.

While that is the version number pops up is correct, but i Need more to see if the patch is correct. For example High sierra needs to have the following version codes, (13604.4.7.1.6) or(13604.4.7.10.6) . Is there anyway to find that out?

Thanks
