In turn the centralized OS authority needs proper maintenance otherwise it's just as bad if not worse, because of the larger blast radius

[–] brookst 1 day ago

I don't know about worse. Imagine a world where there is no OS authority, each app does their own. Do you think all important apps would be updated in 10 days, including auto-updates?

Apple fucked this up, but I really don't think the situation is "as bad if not worse" than if MacOS just didn't do this.

Isn't that the world that Docker gives us, basically?

[–] Shish2k 1 day ago

Yes - difficulty in shipping security updates to a hundred different container images, each of which is vulnerable in their own slightly-different way because they all decided to ship an OS alongside their app - is one of the top criticisms of the docker way of doing things

Just run it in kubernetes and mount the certificates with trust-manager

If it were 5 years ago I'd have the same reaction, but today it's fairly simple to setup a single node deployment with minikube or k3s, and LLM makes it very easy to maintain deployments.

If only we could somehow share libraries and configuration files across apps rather than duplicating them and having to update them for every app individually.

We could call it a "shared library" system and an "operating" system. Someone should really invent this.

I mean, even docker could maybe use a shared base image or something right? ;-)

Now make it immutable and layered, like Docker images, and you might be onto something... Ah well, sounds too good to be true. We might have to nix the idea.

Should it also predate Docker by a decade? That would be crazy.

What kind of psychopath ships 100 distinct container images? I mean, maybe if you’re talking about all of Netflix or something, but… I suspect even they have base images that they use as a starting point.

There’s very little actually running in a docker container. ca-certs may actually be an exceptional case though, since it’s not code that’s running but a kind of data.

It’s not like if you use an Ubuntu image for a node.js app that you get PHP too and have the PHP vulnerability present in your web app.

You still have to rebuild each Application Container with new CACert and deploy them. Depending on teams are working, that can be disruptive.

I would say that if rebuilding your docker containers is a disruptive process, that is a process issue.

[–] stackskipton 1 day ago

I would agree but it doesn't change the fact that many companies do not have CD and have processes that must be followed for rollouts.

It's same problem we have when libraries get massive security vulnerabilities. Updating them is not always as easy as many would like.

AFAIK a container build just puts files into a base image, this creates a sort of a commit chained to the base image commit. This means to update the base image you only need to rebase that commit on top of the new base image branch automatically.

[–] notpushkin 20 hours ago

I haven’t seen tooling for rebasing OCI images yet. Considering you’d still have to do this and roll it out to the server, you can just re-run the CI, which would build the image again, but also test that it works with the new base image.

That's the world we live in now thanks to Google and Mozilla.

[–] emn13 22 hours ago

Surely there's a nuanced difference between "every app distributes this independently" and "a very small few apps that bear the brunt of hostile exposure support independent mechanisms".

It's also worth remembering that both of these specific organizations were instrumental in major, positive security shifts that eventually hit OS's too, including shorter-lived certs, limiting the point of CAs, adoption of TLS 1.3, and likely other things. If anything, they deserve _more_ trust than the OS distributors on this specific front, perhaps also because they don't share the OS distributor's incentive to prioritize stability for paying customers, which can be at odds at times with harsh, prompt security measures.

It makes no sense to imagine this hypothetical scenario and compare it to reality, you have to imagine a similar world with a OS authority, but it only gets updated every 6 months. Which is worse in the worse case? I'd say the one with the lower blast radius.

But this abstract exercise is only to highlight the importance of Apple getting its shit together, because such a scenario exists with Windows and the culture of downloading exes and msis and it's honestly way worse than having a central but responsible authority.

Remember this is the same company that demands they're the only ones who can possibly decide what software their users get to install.
