"Docker versions 1.3.0 through 1.3.1 allowed security options to be
applied to images, allowing images to modify the default run profile
of containers executing these images. This vulnerability could allow a
malicious image creator to loosen the restrictions applied to a
container's processes, potentially facilitating a break-out.
(CVE-2014-6408)

The Docker engine, up to and including version 1.3.1, was vulnerable
to extracting files to arbitrary paths on the host during 'docker
pull' and 'docker load' operations. This was caused by symlink and
hardlink traversals present in Docker's image extraction. This
vulnerability could be leveraged to perform remote code execution and
privilege escalation. (CVE-2014-6407)"
