I think the wrongful notion comes from the fact that the vast majority of Arch users use and speak about AUR as if it were a part of arch proper, only paying lip service to reviewing PKGBUILDS, etc. They wrap the default package manager in one that supports AUR and never touch it directly again. It feels closer to if all of GitHub was available in one click through the Microsoft store or windows update.
And unfortunately that’s how arch is mainly marketed by its users. “Arch has the latest everything, if it’s not in the repos it’s on AUR” is one of the standard selling points.
Of course that speaks to how people use linux insecurely not how Linux is insecure.

Most AUR "helpers" show you the PKGBUILD and/or a diff thereof and ask you to confirm that it looks ok before continuing the install. At least by default.
Maybe most users just ignore that and always answer yes without inspecting it. I don't know. But the wiki for the AUR and Readmes for many of these tools have warning banners telling you not to blindly trust AUR packages.

significantly so. Windows has a coherent story when it comes to permissions and access. Differentiated out access controls, least privilege, UAC, mandatory integrity control and all configured out of the box.
Without AppArmor or SElinux correctly configured, which it isn't on most desktop distributions in the linux world most of your apps can still read anything, there's little sandboxing. The NT Kernel was designed with an object model in mind so you always had the abilities to have rich descriptions and policies for whatever you're handling where all of that is bolted on unix systems after the fact.

I disagree. Maintainers for the major distributions take their roles very seriously, and do a very good job generally of filtering out malicious packages. The AUR is an outlier, being essentially an unmaintained wild west.
saghm 2 hours ago [-]
The AUR is also not really comparable to official distribution package repositories either. Yes, it's hosted by the same people as the official repos that are comparable to what you'd get by default on other Linux distros, but it's intentionally not something that works with official package management tooling. The equivalent would be if Debian or Ubuntu hosted a repo that anyone could upload of unbuilt debian packages while explicitly not offering any tooling other than the usual tools for building a .deb from source files that you manually downloaded from anywhere else or defined yourself.
It's definitely an outlier, but more in terms of being something that doesn't really exist anywhere else, so of course the security model for it will also be an outlier. That's not an excuse for any security issues, but it's not like Arch doesn't have official repos with maintainers who are just as diligent as any other distro. They just also happen to provide a public git server that people can publish packages to with a UI for seeing some of the package metadata; people could just as easily write toolling to automate package management where it looks for a GitHub repo instead of an AUR one to fetch the build files.

I'm sure the team are having a rough time with all this, but I don't understand the path you followed to go from the maintainers have not taken this action until now to "This doesn't speak well to the security headspace of the Arch maintainers". Or what "security headspace" means exactly.
Yes, lots of people thought disabling package adoption is/was a good idea. It seems quite likely that the Arch DevOps team also could have come up with that one, and they certainly wouldn't have missed all of the people telling them to do so.
It seems to me that disabling package adoption is not a desirable thing to do in general, and can only be used as a stopgap response to an emergency, which seems to be what is happening right now.
"just disable adoption" certainly can't be a long-term solution:
Without adoption, the AUR will slowly fade away as orphaning a package would be permanent.
Maybe the idea is to have some sort of approval process to filter adoption requests? In that case the AUR just dies instantly as that would effectively be another official repo with all of the issues that that would bring.

Do you have a solution to ever reenabling package adoptions? It's pretty much a must have feature for this to exist long term, at least in the AUR's current state where its a repo your not supposed to auto install from but pretty much all users do.
Really disabling adoptions is probably step 1 to just EOLing the whole thing.

This can happen to Ubuntu with the PPA's too if someone were to gain control over, say, the Nvidia PPA for drivers. It's happening almost daily with NPM and Github.

IMO allowing package adoption makes sense in the responsible/intended use-case: AUR packages aren’t trusted, you have to read the PKGBUILD anyway, so the reputation of the contributor doesn’t matter.

Which is probably the best choice, unfortunately.

tremon 2 hours ago [-]
With a bit more structure, you could change that to: every package in AUR is actually registered as foo/maintainer under the hood, and installing the package without maintainer name pins it to the currently active version. Package adoption can then be formalized as a new maintainer publishing their own version of the package, and users of an already-installed package need to issue an explicit command to switch over to the new maintainer's version.

WRT package vulns, I'm surprised there's not more technical theory out there. We have plenty of theory around algorithm design, but so far I haven't heard much about inspecting and improving control of dependencies in source - apart from conflict and version management.
Seems like instead of big-O notation, we could have a "reach index" - how far does the top-level code need to reach, to be effective? Top-level -> Userland lib 1 -> Userland lib 2 -> Kernel, would be a reach level "4" - not the simplest, but much simpler to inspect and securely build than reach level "20".

gh02t 2 hours ago [-]
A complication is that AUR doesn't publish packages, it's more like FreeBSD ports in that they are the build scripts for packages and the user builds the package on their local machine. Building an AUR PKGBUILD inherently runs arbitrary code on the user machine, and that code is controlled by the maintainer of the AUR package.
So you have to scan an arbitrary bash script and determine if it pulls malware, or build the package server side in a sandbox and scan it (and some AUR scripts wrap proprietary software blobs the user is supposed to provide e.g. MATLAB, which makes those impossible to build server side). It's a very big extra layer that malware deployments can hide in.
