==========================================================================
Ubuntu Security Notice USN-1326-1
January 11, 2012

nova vulnerability
==========================================================================

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

- Ubuntu 11.10

Summary:

Nova would allow unintended access to resources over the network.

Software Description:
- nova: OpenStack Compute cloud infrastructure

Details:

Nachi Ueno, Rohit Karajgi, and Venkatesan Ravikumar discovered that when
Nova is configured to use the OpenStack API, it would not correctly enforce
access controls on certain incoming requests. A remote authenticated
attacker could exploit this to change resources of arbitrary tenants.

Update instructions:

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

Ubuntu 11.10:
  nova-api                        2011.3-0ubuntu6.4

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