If Lemmy has taught me anything this is a Linux user’s dream because now they can install Linux on the machine.
I’ll admit I have zero insight and haven’t looked into this, but at first glance, I don’t understand why a desktop environment theme engine is unable to provide enough functionality for theme creators to do their thing without resorting to arbitrary command execution…
I trust KDE devs to address this quickly, but this is a pretty major oversight IMO…
“Global Themes” in Plasma do more than just styling
To developers it’s not a surprise that third party plugins can do this sort of thing. It’s as intended. A global theme can ship custom lockscreens, custom applets, custom settings and all of these can run arbitrary bundled code. You can’t constrain this without limiting functionality.

Naturally this is not what an end user expects when browsing for themes, and the warnings don’t make up for the risks.
I hope devs can find a better way to ship this rich functionality, or at least introduce an automated “canary-release” process to the KDE Store that takes down themes that misbehave.
This sounds very amateurish from Plasmas part as allowing themes to run bash scripts sounds like a very bad idea no matter how you look at it.
Themes should probably have something like their own domain specific language (DSL) that can be fed to the “theme engine”(?) which will make the requested changes. If additional functionality is needed it should be provided through separate modules/plugins or something.
My thoughts were sandboxing, so run it in a container with only predefined hooks out. That way you know what parts of the system a theme is wanting to change or access (think flatpak).
I do like the use of subset languages to reduce attack surfaces (eBPF comes to mind as an example definitely not a solution to here those lol).

It’s possible that this deletion was a shell script mistake rather than malice, but it really shouldn’t be allowed either way. It’s made even worse by the UI that encourages users to install themes that that could have been made by anyone, with practically no oversight, and with no warning that they can execute arbitrary code.
I like KDE for a lot of reasons, but I’m ashamed of them for this irresponsible blunder.
Let’s hope they respond by closing this hole and any others like it. If they have to break compatibility with existing themes, now seems like a good time for it, since Plasma 6 was only just released.
Uk this prolly is an unpopular opinion, but KDE just isn’t as stable as it should be. When I used KDE (even when my friend used it) something or the other ALWAYS broke. Like just like that! The wifi icon bar or whatever disappeared. Why? Cuz it wanted to… Uggh it just feels like using alpha software, uk…
NixOS users be like : meh, just rolling back
I keep seeing comments about NixOS. As a relative newby just messing around for themselves, is there anything stopping me from/I should know about taking the plunge?
I’ve only dipped my toe in Ubuntu.
Removed by mod
This is a really good explanation! Thanks.
How is this any different than skeletons and using up ansible, salt or chef? Also hear a lot about Nix but don’t see the OS of NixOS
Removed by mod
And it shares a name with a Bad Dragon toy!
fascinating username to join the conversation at this particular moment in time
I keep wanting to dabble with nixOS as it almost seems like the docker compose of OS’s
But every now and then someone comments and acts like it’s really hard or something.
I so scared
If you can wrap your head around docker compose, you can handle nix.
That is to say, I’d sounds like you aren’t afraid of tinkering and looking at other people’s solutions until you get your setup right. That’s what NixOS is all about.
Solve that problem once, you’ve solved it forever. You don’t need to remember how you did it next time.
Now, THATS something I can get behind.
I daily drive it on 2 machines. Overall, it is super simple, if you know how to ready json or yml, you will understand the config file instantly. However, it is a unique OS, and works different than most other distros. As a result, any guide made for other Linux distros needs to be thrown out the window. It also doesn’t natively support most self executing packages like app image. All that said, it is fun and easy, just make sure when you look for support, you are looking for NixOS support.
Neon explained it better than I ever could! I hope their answer satisfies you
It did! Thank you for sparking the conversation.
nixos is like the hyper power user OS i think. Think of it like unixporn, if you like spending hundreds of hours perfecting your rice, you will love nixos (probably) if not, and you dont really care (like me) go use debian or arch or something else instead.
But the script only deleted files in /home
Imagine not having a backup of your files 😳
I don’t actually. All stuff I care about is on code hosting platforms
That whole feature needs a reboot, to be more like wallpaper engine.
I know this story is more-so about a trojan in a trusted place, and not general security, but I have an anecdote to share.
So, time to fess up here. I previously complained about Google trapping me in captcha-hell for enabling Ublock Origin.
I was wrong.
Turns out that I had visited a movie streaming site a while before to watch a season of some show, I forget which. Without any downloads or noticeable input on my part. My Linux box apparently got hacked/malware. All I did was click the occasional “I am a human” box on the website, and sit back with popcorn.
I found out when my ISP starting blocking IP addresses some time later. I checked my modem’s logs, and they showed some unexplained traffic to impossible “unassigned” IP addresses afterward. I didn’t notice for a while.
I was stupid. Even worse, my phone also started behaving badly after that. I think I watched the last few episodes in bed, so must have infected that too.
Don’t assume any system is automatically safe.
I really doubt anything escaped the browser, but websites can make nefarious connections, sure.
I hope so. It’s more likely something infected Firefox itself, and didn’t get into the OS. But when I checked the modem logs, it happened up to a couple of months after the fact. That’s worrying.
What’s even more worrying is that a couple of websites told me I had an IP address that didn’t match my home IP, but would provide the correct one if I refreshed the page a couple of times. So some kind of covert proxy or VPN type of thing was happening.
I ended up just wiping everything, to be safe. Still a bit paranoid though.
deleted by creator
As a KDE user and a very new Linux user, this is a little disappointing. I’m glad it didn’t happen to me.
Use Firefox Translate please ;D
Trick: use Firefox translate, export website using singlefile, share the website as html.
Oops. This is why you install themes from sources you trust.
This came from the KDE theme store. Most Plasma users trust KDE.
Yes, but KDE store does not suggest checking them at all. Unless you are curious you won’t know that themes can run scripts.
Would this be possible to fix on btrfs, or would you have to create a snapshot first?
The “fix” would be to not allow themes to execute code in the first place.
I mean once files are deleted maliciously or accidentally
you would need to have created a snapshot beforehand.
Then you could restore to the last snapshot. But you would need a live system to do that, if your installation is broken
