Description Laura Pardo 2018-05-14 15:52:25 EDT

A flaw was found in cri-o up to version 1.10.2-dev. Pod workloads fails to drop capabilities when switching to a non-root
user. This allows a non root user to create a pod and start it successfully even when the container needs privileged permissions.
