runc container escape via "masked path" abuse due to mount race conditions

Impact The OCI runtime specification has a maskedPaths feature that allows for files or directories to be "masked" by placing a mount on top of them to conceal their contents. This is primarily intended to protect against privileged users in non-user-namespaced from being able to write to files o...
