It's not fully sandboxed if it can write to my screen! That filthy app, writing stuff all over the place!

[-] gentooer@programming.dev 41 points 7 months ago

Haskell programmers when you tell them the main function isn't pure

Sandboxes have been converted into quarantine bomb shelters, for child safety

That's why we have Wayland. :)

[-] darth_tiktaalik@lemmy.ml 132 points 7 months ago

I like how the app name is blacked out so as not to dox the flathub app.

[-] Helmic@hexbear.net 40 points 7 months ago

Wouldn't want bad actors to find privacy respecting software.

[-] radioactiveradio@lemm.ee 35 points 7 months ago

Sanboxed from prying eyes, it's completely safe.

[-] Strit@lemmy.linuxuserspace.show 124 points 7 months ago

What if your app actually needs access to the internet?

[-] tony@lemmy.hoyle.me.uk 134 points 7 months ago

Or actually do anything useful? No network, no filesystem.. it's a hello world app isn't it..

[-] snowfalldreamland@lemmy.ml 37 points 7 months ago* (last edited 7 months ago)

There are portals: https://docs.flatpak.org/en/latest/desktop-integration.html#portals . they allow secure access to many features. Also any flatpak app still has access to a private app-specific filesystem, just not to the host.

Doesn't work for all applications but for many sand boxing is possible without a loss of features.

[-] IverCoder@lemm.ee 24 points 7 months ago

There's Obfuscate, an image redactor, and Metadata Cleaner which is self-descriptive. Both works properly without any filesystem access at all, because they use the file picker portal to ask the user for the files to be processed.

Oh come on, what modern program actually needs to communicate or access the file system?

[-] Theoriginalthon@lemmy.world 33 points 7 months ago

Exactly all programs should be web based cloud subscription only. We don't want that filthy code on our rgb nvme drives

The app can then declare the network permission and it will still be marked as safe.

[-] QuazarOmega@lemy.lol 19 points 7 months ago

Download the internet along with it!

[-] ivanafterall@kbin.social 27 points 7 months ago

I'm self-hosting the entire internet. I hope you guys are enjoying yourselves.

[-] QuazarOmega@lemy.lol 6 points 7 months ago

Thanks for having us on your server... when can I get out again though?

[-] ivanafterall@kbin.social 8 points 7 months ago

I just unplugged you. Give it a minute or two and no more pain.

I remember in 1995-ish or something when I used the internet for the first time using the Netscape browser.... And I was asking a friend if he had tried all the web sites yet. Just got a weird look back.... :) I didn't know what the internet was back then at first.

What really needs to happen:

Flatpak packages should ask for every permission they need, and the user needs to approve every one of them.

Right now, we have this weird in-between state where some flatpak packages ship with limited permissions (like Bottles). That's because every permission the package asks for is immediately granted. The user doesn't get a chance to refuse these requests. This current model serves to make life more difficult for non-malicious flatpak packagers while failing to protect users from malicious packages.

Also, GNOME needs a Flatpak permissions center like KDE. You shouldn't need to install a third party program to manage permissions.

[-] JoYo@lemmy.ml 20 points 7 months ago

it’s weird that android and ios already provide this but THE container standard doesn’t

[-] miss_brainfart@lemmy.ml 15 points 7 months ago

Absolutely, permissions should be disabled by default, and only when the app needs to do something that requires a certain permission should it ask for it.

Maybe even do something like Android, where permissions automatically get revoked if you don't use an app for a certain time. I love that feature.

I've tried to combat this a bit with a global Flatpak override that takes unnecessarily broad permissions away by default, like filesystem=home, but apps could easily circumvent it by requesting permissions for specific subdirectories. This cat-and-mouse game could be fixed by allowing a recursive override, such as nofilesystem=home/*.

But even then, there is still the issue with D-Bus access, which is even more difficult to control ...

I think it is sad that Flatpak finally provides the tool to restrict desktop apps in the same way that mobile apps have been restricted for a decade, but the implementation chooses to be insecure by default and only provides limited options to make it secure by default.

!peepee !< is safe

[-] Blackmist@feddit.uk 33 points 7 months ago

Likes like Hello World is ready to ship.

[-] IverCoder@lemm.ee 27 points 7 months ago* (last edited 7 months ago)

With a bit of modifying code to use the color picker and maybe rearranging the workflow to adapt to the new system, apps as advanced as DaVinci Resolve and LibreOffice can have permissions as restrictive as this (the network permission would of course may be needed but it would still be marked as Safe by Flathub).

You can use the file picker API to open the files or folders your app would need to access while having no filesystem permissions at all. You can access the camera, microphone, and GPS without the user devices portal, by simply using the respective portals where the user has the power to allow or deny access to such devices as they wish.

You can record the screen, take a screenshot, and pick a color in the screen by simply calling the proper portals, with the bonus that the user will be able to select if they want the entire screen, a specific window, or a specific area to be recorded/captured and whether the cursor should be shown or not.

Heck, even TeamViewer can be as this restricted without losing any functionality if they use the Screen Cast portal which allows apps to mirror input from a remote device! They would of course need the network permission, but that's still safe.

This kind of thing could work for a few apps, say a color picker utility or a QR code generator etc.

Looking at the docs, it isn't clear if apps can write to their own namespace (instead of writing to user folders directly), but if they can, we could expand the scope to games like supertuxkart, 2048 etc, which would then be able to save user milestones and progress in their own area - a bit like how Android apps do it

https://docs.flatpak.org/en/latest/sandbox-permissions.html

It's a great start IMO, although admittedly there is still work to do. Flatpak atm bridges the gap with allowing new apps, requiring new libs, to run on older stable/LTS distros

[-] themoonisacheese@sh.itjust.works 17 points 7 months ago

Yes, they can. There are app-specific folders in .local that flatpaks can read and write to specifically for this purpose, and also the file picking dialog may give access to the one specific file you picked.

Android IMO has great usability in exposing a database to apps, which means they aren't required to ship their own database engine.

this sandbox craze is slowly pushing things back to the point where we used cartridges and booted off from them straight to the program. who needs an OS at this point? it's bundled with the app anyway 😆

/s, somewhat

[-] soulfirethewolf@lemdro.id 22 points 7 months ago

It's nice to see good app security being praised. Sometimes it feels like some people on lemmy (and the fediverse) throw security to the wind.

Like one time I had heard someone over on Mastodon say that they thought that HTTPS was too overused and shouldn't have been everywhere because it makes older apps unable to access sites and also made adblocking just ever so slightly harder.

Which yeah, I love adblockers, but I'm definitely not comfortable with all traffic having to go unencrypted just for it.

[-] JustARegularNerd@aussie.zone 6 points 7 months ago

But my 1998 Windows CE device that's made obsolete by those meddling modern security practices!

[-] Drito@sh.itjust.works 20 points 7 months ago

This is useful for proprietary software.

[-] IverCoder@lemm.ee 33 points 7 months ago* (last edited 7 months ago)

As well as FOSS too. Sandboxing is a security standard that should be followed by every software how open their code may be.

[-] bizdelnick@lemmy.ml 12 points 7 months ago

What is this? A solitaire game?

[-] IverCoder@lemm.ee 11 points 7 months ago* (last edited 7 months ago)

This could well be an advanced video editor or an office suite if they take full advantage of the portals API without losing any functionality. Well, they can have the network permission, it would still be safe anyway.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
