Title:
  Sanitation of metadata label

Status in OpenStack Dashboard (Horizon):
  Fix Committed
Status in OpenStack Security Advisories:
  Triaged

Bug description:
  1) Start up Horizon
  2) Go to Images
  3) Next to an image, pick "Update Metadata"
  4) From the dropdown button, select "Update Metadata"
  5) In the Custom box, enter a value with some HTML like '</script><script>alert(1)</script>//', click +
  6) On the right-hand side, give it a value, like "ee"
  7) Click "Save"
  8) Pick "Update Metadata" for the image again, the page will fail to load, and the JavaScript console says:

  SyntaxError: invalid property id
  var existing_metadata = {"

  An alternative is if you change the URL to update_metadata for the
  image (for example,
  http://192.168.122.239/admin/images/fa62ba27-e731-4ab9-8487-f31bac355b4c/update_metadata/),
  it will actually display the alert box and a bunch of junk.

  I'm not sure if update_metadata is actually a page, though... can't
  figure out how to get to it other than typing it in.
