>Linux distros are behind on implementing modern binary exploit mitigations.
Compile from source, use only trusted package managers, and sandbox and compartmentalize when possible.
>Linux distros have no concept of sandboxing
They may be inadequate or need improving, but these concepts are there, if rarely used by default.
>Any app running under Xorg can see the contents of any other app runing under Xorg.
There are ways to prevent this without saying "Wayland".
>The only good sandoxing API provided by the Linux kernel is seccomp-bpf, and the only program that uses it is Google Chrome/Chromium.
The very link to the wikipedia entry for seccomp shows otherwise...
>Also a friendly reminder that Debian is always behind on CVEs, and I'm sure that most distros don't fare any better.
This is a good point, and one of the reasons I think that the future will belong to rolling release style distros with a faster CVE cycle.
Just the few things that stood out to me, not a piece by piece analysis.
- noobermin 6y agoWhat mitigations exists for the Xorg apps?
- arminiusreturns 6y agoQubes, running rootless helps but doesnt stop it, xephyr with selinux sandboxes, nothing that completely fixes the issue.
