Gitlab-runner was built manually (no aarch64 packages available): On a system with Linux namespaces enabled and working: CI pipeline succeeds (user and mount namespaces are unprivileged). However, one of the researchers who found it has posted a proof of concept showing a container breakout, and it's expected that exploit code will be released soon. Sign in For unprivileged containers, ensuring that a seccomp filter is in place that blocks the unshare call will reduce the risk. However, this only seems to work if the virtual node Singularity launches into happens to be the Docker container with the highest PID number (most recently spawned).
