One of the files on their server is an exploit for that vulnerability. If they know about it, I would guess they aren't vulnerable, but who knows.

Good point. The kernel version in the transcript looks like the version I've got on a CentOS machine, so it's probably patched. Interestingly, the strings ("r00tr00t", "Executing shell") from the local-root tool they're using don't appear anywhere online, suggesting that it's something private and potentially unknown.

maybe it's just not indexed.

It's easy to modify strings in a simple C function/program. That's all that would be needed to modify and display the "r00tr00t" etc you are mentioning.
