If Apple released a patch in less than 24 hours I’d be seriously concerned about the QA that had gone into the patch.

I guess you’re seriously concerned now ;)

I guess so. I hope they QA’ed it better than they did the previous version...

Just in case it is relevant for anyone here this is what our security team have established thus far: - Can be mitigated by enabling the root user with a strong password - Can be detected with `osquery` using `SELECT * FROM plist WHERE path = "/private/var/db/dslocal/nodes/Default/users/root.plist" AND key = "passwd" AND length(value) > 1;";` - You can see what time the root account was enabled using `SELECT * FROM p…

I see a lot of comments here wondering why Apple seems to not care about software quality anymore. I don’t know if that’s true, but there’s a perfectly obvious answer: They don’t have to. Software quality in macOS was important back when they were trying to get people to switch from Windows-based PCs to Macs. Nowadays, most people who were going to switch have already switched, so Apple has no incentive to keep up th…

Nah. At this rate people will simply abandon the ship sooner or later. There's definitely some deterioration going on instead of only a cynical strategy shift.

The new MBP isn't attractive anymore. The software stagnates. The only reason I keep using Mac for usual use cases is just its wonderful collection of dictionaries (I like to constantly learn new languages). I wonder why no publisher ever bothered coming up with a decent dictionary software on Windows/Linux yet instead of making do with crappy online versions. If they did I'd happily just use a Windows + Linux dual boot machine.

But someone at Apple got their bonus for shipping the animated poop icon in time for this release.

If you think the team that makes animojis is the same team in charge of security or QA, I have news for you.

If you think Apple's management aren't 100% responsible for what people and budget is allocated to each team, I have news for you too...

One of my Macs is showing a root password change date of Nov 10th 2017. I can't explain that, so I'm reinstalling now. It did have sshd enabled and remotely accessible, though I thought root login was prohibited. If I understood correctly, this particular bug was only exploitable from the GUI and this machine hasn't been away from home, so it's likely this isn't related, but posting here, in case it's part of a bigge…

possibly the same timestamp here: 1510300538.767916 'Fri, 10 Nov 2017 04:55:38'

Oh wow. Is there any other explanation for this other than this having been exploited in the wild for almost three weeks? Or maybe someone just tried to log in over SSH to exploit some other weakness (something like predictable SSH passwords on jailbroken iOS devices), and happened to create the root user on your machine?

Did you also have sshd running, and do you know what kind of network you were using at the time?

This works remotely as well (although not through SSH, obviously).

Apparently they broke an aspect of network file sharing with this quick-turnaround patch. Whoops.

> I still can't believe more people complain about this being publicly disclosed than this being possible in the first place. I think the problem is due to the fact that they are fans. In this case, it's Apple, but there's no reason it couldn't be Linux or Go or whatever. Regardless, any bad news about their hero is irresponsible to disseminate. We see this same phenomenon in politics, in sports and elsewhere — I dar…

I've not commented either way on the subject in this thread, but personally I would much rather have read this as a writeup 2 or 3 months from now after the discoverer had responsibly disclosed the vulnerability and Apple had a chance to patch it. On the other hand, I'm glad that I have this information so I know not to install High Sierra on my work iMac (sitting on a desk in a WeWork behind a door whose lock would…

As an addendum apple released a fix for this less than 48 hours after it was reported (I think I've got the timeframe right), so there's something to be said for irresponsibly disclosing to light a fire under the ass of whomever is responsible for fixing a vulnerability.

That is not the case among infosec professionals either. Many respected professionals believe that the right thing to do in many cases is full public disclosure. Google Project Zero are a notable example.

Which respected professionals ? This is completely false.

No, it isn't. DJB is an easy one. I won't name others, but I know, and know of, many.
