Nothing but click-bait.
If this was a true problem, it would have been fixed.
The last I heard, Microsoft acknowledged it and promised a fix. I haven't seen it appear yet.
Are you saying that until they provide a fix, it is by definition a false problem, and only becomes a true problem afer it's been fixed?
Only half-joking... :)
It's a true vulnerability. How big an issue is it? SMB is done mostly within the confines of a local network where attacks are mitigated by firewalls and such. So yeah, this is small compared to the SSL vulnerabilities, for example, because they are attackable over the internet.
It is a real problem as it can be used to push a user’s security hash to the attacker. That then allows an offline attack against the hash which can reveal the password.
