========================================================

:Date: February 23, 2015
:CVE: CVE-2014-9684, CVE-2015-1881


Affects

- Glance: 2014.2 versions through 2014.2.2


Description
~~~~~~~~~~~
Abhishek Kekane from NTT and Mike Fedosin from Mirantis reported a
vulnerability in the Glance import task. By creating numerous images
using the task API and deleting them, an authenticated attacker may
accumulate untracked image data in the backend resulting in potential
resource exhaustion and denial of service. All glance setups using API
v2 are affected.
