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

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

- Ubuntu 14.04 LTS

Summary:

OpenStack Nova could be made to expose sensitive information.

Software Description:
- nova: OpenStack Compute cloud infrastructure

Details:

Garth Mollett discovered that OpenStack Nova did not properly clean up an
instance when using rescue mode with the VMWare driver. A remove
authenticated user could exploit this to bypass intended quota limits. By
default, Ubuntu does not use the VMWare driver. (CVE-2014-3608)

Amrith Kumar discovered that OpenStack Nova did not properly sanitize log
message contents. Under certain circumstances, a local attacker with read
access to Nova log files could obtain access to sensitive information.
(CVE-2014-7230)

Update instructions:

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

Ubuntu 14.04 LTS:
  python-nova                     1:2014.1.3-0ubuntu1.1

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