My question is inspired by apples
goto fail; bug.
I am wondering if the bug is really as dangerous as it is propagated everywhere. The reason I am in doubt about that is that there is a MITM attack required to abuse the bug, isn't it? And if this is the case then the only point this becomes dangerous is in public WIFI's or hotspots or anything like this. Or I understand this wrong and there are possibilities to be MITM-attacked from outside, that means in between two ISP routers for for instance?
Don't get me wrong, of course I know this is very dangerous, but is it still dangerous if I am only connected to the Internet through my private LAN?
