Fellow Linux users, please keep the snark in this thread to a minimum. Here's just one recent example why, there are more: http://www.omgubuntu.co.uk/2017/05/ubuntu-guest-sessions-log...
Linux didn't have that problem, a single vendor did. You could say the same for Apple except they are the single vendor. That stupid security trick in Ubuntu only impacts subset of a subset of Linux _desktop_ users which is a pretty small subset of computer users as a whole. When Apple does something like this, it impacts a much larger share of the world population.
So how about we keep the snark to an appropriate level based on the impact to the world population? ;)
So lets keep the snark to an appropriate level, shall we?
We can point to avenues for remote root all day but I don't recall any that are/were as simple as "just hit [enter] to get root" that impacts the shared attack surface that impacts all Linux systems.
NOTE: I did not go and search NVD before writing this reply but I did stay at a Holiday Inn Express once.
These sorts of bugs can happen anywhere. We all need to bear that in mind.
One notable difference, though, is that macOS is proprietary software. Apple have sold their users a product and haven't respected their users' right to use, modify & distribute that product; their users have never had the ability to inspect the macOS source for this kind of problem. Thus, responsibility for this disaster rests solely on Apple's shoulders.
