Ubuntu 12.04 LTS USN 1466-2 Moderate: Nova Network Issue Fix

An issue in Nova linked to USN 1466-1 impacts Ubuntu versions that necessitate critical fixes.
USN 1466-1 introduced a regression in Nova.

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.
