Description
In Kubernetes versions 1.3.x, 1.4.x, 1.5.x, 1.6.x and prior to versions 1.7.14, 1.8.9 and 1.9.4 containers using subpath volume mounts with any volume type (including non-privileged pods, subject to file permissions) can access files/directories outside of the volume, including the host's filesystem.
It was found that volume security can be sidestepped with innocent emptyDir and subpath. This could give an attacker with access to a pod full control over the node host by gaining access to docker socket.
