For those not in the know: aussie man explains. A KDE Plasma 6 global theme deleted a user's files. Global themes may contain arbitrary Javascript code, and a bug (using a library written for Plasma 5) caused it to essentially run rm -rf /*, Steam-style. KDE have since removed the theme and are considering next steps to warn the user that the "official" KDE store contains user-submitted content, and that some addons may contain potentially dangerous code.

I still remember that video I watched where a line in the Steam code back in the day was titled SCARY!!!!! and it was rm -rf $STEAMROOT. This nuked a guy's computer because short answer $STEAMROOT was actually / root, long answer here's the video. This nuked both his PC and his external drive that is some pretty bad code but this JavaScript code is up there

That's the issue I linked. The problem was that at some point a script executed rm -rf "$STEAMROOT/*", but did not make sure that $STEAMROOT was set. If for some reason it was empty, the path became /* after substitution.

So would it be funny if I made a meme like this except it was with the trojan horse meme template? I kinda want to

Is this affecting both plasma 5&6 then?

[-] [email protected] 4 points 1 year ago

This particular issue was caused by a breaking change in Plasma 6 and bad handling in a specific global theme.

The general security concerns that were being brought to light however apply to all versions.

[-] [email protected] 4 points 1 year ago

It should only affect Plasma 6 because of some breaking change to how a Javascript function returns a path.

It's only 3 layers deep, shame on you and your laziness

I will await the 100 recursive layers SVG version later today, do not disappoint me (please).

I'm afraid I didn't make it and just stole it

[-] [email protected] 36 points 1 year ago

Gottem

Seriously though we need to work on improving security. A theme probably shouldn't be running code and if it is it needs to be sandboxed with its only access being an API

[-] [email protected] 12 points 1 year ago

It's kind of horrifying nobody thought that through. What else did they fail to think about?

[-] [email protected] 2 points 1 year ago

I know I'm late with this but it's not just a theme. It's a global theme. Those need to run code, so they really can't be sandboxed the same way a regular theme can be

[-] [email protected] 31 points 1 year ago

Why do themes need to run code?

[-] [email protected] 3 points 1 year ago

They shouldnt. At least use some kind of super locked down API if you're gonna let people use javascript of all things in your theming system god damn

[-] [email protected] 6 points 1 year ago

Actually I'm pretty sure C would be much worse

[-] [email protected] 1 points 1 year ago

Well, you can literally create a C program in bash using themes, compile and execute it.

Real "What does God need with a starship?" energy.

[-] [email protected] 1 points 1 year ago

People in one of the other threads were speculating that it is widgets, or one theme that is able to do multiple configurations. Really should be containerized or something, tho.

[-] [email protected] 1 points 1 year ago

Setting themes do mant things and they are not like adding a colorscheme or so. Like there are tweaks that comes wuth themes which needs shell access to heavily modify the desktop

[-] [email protected] 1 points 1 year ago

So they can include cool features like auto debloating /home/

[-] [email protected] 21 points 1 year ago

Theme applied successfully!

[-] [email protected] 1 points 1 year ago

Yeah, shouldn't it say something like "ha ha get fucked"?

[-] [email protected] 14 points 1 year ago

is this the reason Bleeping Computer made that article about malicious KDE themes? i saw it in my feed but didn't think much of it
