Ubuntu Security Notice USN-1626-1
8th November, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.10
- Ubuntu 12.04 LTS
Glance could be made to delete arbitrary images.
- glance - OpenStack Image Registry and Delivery Service
Gabe Westmaas discovered that Glance did not always properly enforce access
controls when deleting images. An authenticated user could delete arbitrary
images by using the v1 API under certain circumstances.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 12.10:
- python-glance 2012.2-0ubuntu2.2
- Ubuntu 12.04 LTS:
- python-glance 2012.1.3+stable~20120821-120fcf-0ubuntu1.2
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
