CVE-2015-5251
A flaw was discovered in the OpenStack Image service (glance) where a tenant could manipulate the status of their images by submitting an HTTP PUT request together with an 'x-image-meta-status' header. A malicious tenant could exploit this flaw to reactivate disabled images, bypass storage quotas, and in some cases replace image contents (where they have owner access). Setups using the Image service's v1 API could allow the illegal modification of image status. Additionally, setups which also use the v2 API could allow a subsequent re-upload of image contents.
