## Overview

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.

## Affected packages

- `glance < 11.0.0a0`

## Remediation

Upgrade to a patched release:

- `glance 11.0.0a0`
