Title:
  Non-admins can create public images

Status in OpenStack Image Registry and Delivery Service (Glance):
  New
Status in OpenStack Security Advisories:
  Won't Fix
Status in OpenStack Security Notes:
  New

Bug description:
  Glance documentation (
  http://docs.openstack.org/developer/glance/glanceapi.html ) states:

  > Note Use of the is_public parameter is restricted to admin users.
  For all other users it will be ignored.

  However, this is not true on havana, ie. with horizon:

  - user a uploads an image with is_public checkbox **checked**,
  - user b logs in and can see that image in /project/images_and_snapshots/

  It is reproducible with the command line of course:

  vagrant@precise64:/opt/stack/horizon$ glance --os-username aa --os-password aa --os-tenant-name aa --os-auth-url http://127.0.0.1:5000/v2.0 image-create --is-public True --name hacked --disk-format qcow2 --container-format bare --file cirros-0.3.2-x86_64-disk.img

  Potentially, a malicious user could upload an image with a backdoor
  and make it available to the public.
