    Summary: OpenStack Glance improper validation of the image_size_cap configuration option

    Details: OpenStack Image Registry and Delivery Service (Glance) before 2013.2.4, 2014.x before 2014.1.3, and Juno before Juno-3, when using the V2 API, does not properly enforce the image_size_cap configuration option, which allows remote authenticated users to cause a denial of service (disk consumption) by uploading a large image.
