Is that a hidden command? ‘Cause this is all I get:

does ‘utils vmtools status’ tell you what you’re looking for (i.e. ‘out of date’ or current)? Or are you looking for more info than is generated by that command?

My colleague helped me confirm that the initramfs timestamp changes when VMtools is upgraded. I’m going to see if TAC can help by logging in as root and getting a timestamp on the file.

We’ll still plan for a possible issue, but at least this will give us a sense of how possible the problem is.

Can I see when the last VM tools upgrade happened? We’re on an isolated VM infrastructure, but had partner work done and I wasn’t involved.

Am I missing something? I mean the way I’m reading it plus the bugs is that if you are on that version and do a vmtools upgrade automatically it can happen?

To me that means every system is vulnerable to the issue. But a second workaround is just disable the auto vmtools upgrade option. As long as one hasn’t happened you are fine.

Not every system on those affected versions is vulnerable.

What do you mean? It lists the affected releases and the ones with the fix?

It’s too bad they don’t have instructions on how to check if you are vulnerable. Not that I could figure out anyways. At least there’s a work around. Now to find that recovery disk image.

Maybe you won’t be rebooting it if you don’t patch out for this one
