horizon vulnerability
============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10

Summary:

OpenStack Horizon did not properly process Heat templates.

Software Description:
- horizon: Web interface for OpenStack cloud infrastructure

Details:

Cristian Fiorentino discovered that OpenStack Horizon did not properly
perform input sanitization for Heat templates. If a user were tricked into
using a specially crafted Heat template, an attacker could conduct
cross-site scripting attacks. With cross-site scripting vulnerabilities, if
a user were tricked into viewing server output during a crafted server
request, a remote attacker could exploit this to modify the contents, or
steal confidential data, within the same domain.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.10:
  openstack-dashboard             1:2013.2.3-0ubuntu1.1

In general, a standard system update will make all the necessary changes.
