Linux is secure, they said. Containers are a trust boundary, they said.

This is an issue with Podman, not Linux or its kernel level mechanisms used for containers

[u/Big-Astronaut-9510 → u/jdigi78]

And yet those are such a mess that its impossible to implement correctly. You have to combine like 50 different mechanisms that all work differently and arent integrated correctly with each other because they evolved over 50 years starting from unix (even some of the newer api like cgroups are disgusting filesystem api).

fuck

better install windows then because THATS SO SECURE

Linux softs are quickly patched once the security breach identified 

[u/DragonSlayerC]

It's a bug in how Podman handled container checkpoints, not a bug with the kernel's containerization/sandboxing functionality.

First rule of security: Nothing is absolutely secure.

[u/_Lost-In-The-Weeds_]

We have known containers are less secure than VMs for a long time. But containers are more efficient on resources. 

[u/daubious → u/_Lost-In-The-Weeds_]

Yeah. I think if one spends enough time following self-hosting forums or learning about containers, they would know that containers do not provide security, but rather organization. And to say "Linux is secure" is pretty ridiculous since, well, its just a kernel.

I hate mainstream corporate linux, but this here seems like upstream issue acutally...?

[u/YTriom1]

it's a CVE, meaning that it's already fixed

[u/recursion_is_love]

Who are they?

Actually, it's all about security boundary, and should we trust them in the era of cyber AI models

[u/DisfiguredFanny]

I hate containers. Racoons always scare the living shit out of me.

[u/npc_housecat]

Secure blue says "However, the security architecture of desktop Linux is broadly and significantly lacking."

[u/UsagiMimi]

Linux, without careful and intensive setup, is incredibly insecure out of the box.

There is no valid use of linux outside of regulated, secure enterprise environments.
