Does a containerized process running with a group ID of 0 present a security risk in case of a container runtime escape ?

Solution Unverified - Updated -


  • Let's take the scenario where someone has managed to escape the container onto the underlying host. Now that user will have a GID of 0 (appreciate UID will be non-root). Hence now we need to factor in the impact of having access to any files with GID of 0. How are we protecting against this ?
