It's an uncontrolled free-for-all disguised as a watering hole. If they can't do the most basic of housekeeping it should not exist full stop.
The officially maintained repositories (which are part of a default installation) were not affected. Users need to go somewhat out of their way to use an AUR.
The definition files are all plain text and not especially complicated. It's not too difficult to glance at the file before doing an install to get a basic idea of what it's about to do, just like you should do when running a random shell script or cloning a random git repo. Indeed, most AURs are implemented by cloning an upstream git repo and configuring it so it can be built. The same basic threat model applies: Do you trust the install script? Do you trust the upstream URL whose code it is about to compile?
it would be better if there were stronger community moderation and review that has stamps i can trust rather than this idea that eyeballing build scripts is a reasonable security posture.
Ok, so instead of having a reasonable security posture yourself, you'd rather rely on a number of random strangers who've eyeballed the PKGBUILD instead?
Generally, I think Arch tries to prevent users from relying on bad signals, and this principle might be applied here too.
> i read all the pkgbuild diffs, still doesn't give me a good sense. sure,
Do you have an example of a diff that doesn't give a good sense? I review all my diffs too, but I feel like all of them give me a good sense if it's safe to install or not. I mean, why would I otherwise, what's the point in reviewing if you don't use it to make a decision if to install it or not?
What else do you have to review? Both in the cases of binaries and source, the idea is that you trust upstream already, otherwise you shouldn't install software from them. And since you trust upstream, the only thing you need to review in the PKGBUILD is quite literally: Where is this stuff coming from, is it the official domain/repository? Are there other non-official dependencies? Are there patches applied?
Once you've reviewed those, you're done, and as safe as if you installed straight from upstream, zero false sense of security here.
You're mixing concerns here, as what you describe is completely different issue.
there is work involved in figuring out how to get the complete diff of the code and dependencies that are included in the change, plus review time. this could range anywhere from 5-10m to 1h per package updated- if not more.
The only way you could possibly not be aware of the AUR's nature as an "uncontrolled free-for-all" is if you didn't read the Arch Wiki, and anyone who doesn't read the Arch Wiki should not be using Arch Linux to begin with.
"Uncontrolled free-for-all" is exactly the status quo of programming language package managers such as npm and pip. It's just as easy for total randoms to sign up for an account and push packages on those services as it is to push a package to the AUR. Only the AUR made the lack of trust explicit and part of the culture.
PKGBUILDs are not packages. They’re (user-contributed) instructions on how to build packages.
> available through the OS's repos.
No. The AUR is a platform, similarly to NPM or PyPI, that allows users to upload PKGBUILDs. It is not part of “the OS’s repos,” and it says that loud and clear, multiple times, including on the front page.
