SECURITY: tags are used without sanitization
As a user, I can do:
pulp-admin docker repo tag --repo-id test-docker --tag-name
which will result in the repo publishing the image as /var/lib/pulp/published/docker/v2/web/test-docker/manifests/just:kidding
(instead of under /var/lib/pulp/published/docker/v2/web/test-docker/manifests/2/)
It doesn't look like you can escape the repository directory structure with a cleverly crafted tag, but you can most certainly put a v2 image in the v1 namespace.
I think tags should follow a directory structure normalization, and any ../ should be stripped out.
