Ubuntu Security Notice USN-1466-2
June 12, 2012

nova regression
==========================================================================

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10

Summary:

USN 1466-1 introduced a regression in Nova.

Software Description:
- nova: OpenStack Compute cloud infrastructure

Details:

USN 1466-1 fixed a vulnerability in Nova. The upstream patch introduced
a regression when a security group granted full access and therefore the
network protocol was left unset, causing an error in processing. This
update fixes the issue.

We apologize for the inconvenience.

Original advisory details:

It was discovered that, when defining security groups in Nova using
the EC2 or OS APIs, specifying the network protocol (e.g. 'TCP') in
the incorrect case would cause the security group to not be applied
correctly. An attacker could use this to bypass Nova security group
restrictions.

Update instructions:

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

Ubuntu 12.04 LTS:
python-nova 2012.1-0ubuntu2.3

Ubuntu 11.10:
python-nova 2011.3-0ubuntu6.8

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