Description Patrick Griffis 2023-02-27 09:44:16 PST

Bubblewrap 0.8.0 released with a new feature that allows disabling namespaces without relying on syscall filters.

This should be more robust and make some classes of exploits impossible.

You can see a writeup on this feature here: https://github.com/containers/bubblewrap/pull/488
And usage of it here: https://github.com/flatpak/flatpak/pull/5084

One open question is do we hard depend on bwrap 0.8.0 or conditionally use this feature.

Definitely should be conditional.

Or, check the output from “bwrap --version” at runtime.
