Ubuntu Security Notice USN-1565-1
13th September, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
OpenStack Horizon could help expose sensitive information.
- horizon - Web interface for OpenStack cloud infrastructure
Thomas Biege discovered that the Horizon authentication mechanism
did not validate the next parameter. An attacker could use this to
construct a link to legitimate OpenStack web dashboard that redirected
the user to a malicious website after authentication.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 12.04 LTS:
- openstack-dashboard 2012.1.3+stable~20120815-691dd2-0ubuntu1.1
- python-django-horizon 2012.1.3+stable~20120815-691dd2-0ubuntu1.1
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.
