detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.

Description

OpenStack Image service (glance) provides discovery, registration, and
delivery services for disk and server images. It provides the ability to
copy or snapshot a server image, and immediately store it away. Stored
images can be used as a template to get new servers up and running quickly
and more consistently than installing a server operating system and
individually configuring additional services.

A flaw was discovered in the OpenStack Image service 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. (CVE-2015-5251)

A race-condition flaw was discovered in the OpenStack Image service.
When images in the upload state were deleted using a token close to
expiration, untracked image data could accumulate in the back end.
Because untracked data does not count towards the storage quota, an
attacker could use this flaw to cause a denial of service through
resource exhaustion. (CVE-2015-5286)

Red Hat would like to thank the OpenStack project for reporting these
issues. Upstream acknowledges Hemanth Makkapati of Rackspace as the
original reporter of CVE-2015-5251, and Mike Fedosin and Alexei Galkin of
Mirantis as the original reporters of CVE-2015-5286.

All openstack-glance users are advised to upgrade to these updated
packages, which correct these issues. After installing the updated
packages, running Image service services will be restarted
automatically.
