The Ubuntu Security Notice USN-1466-1 addresses a nova-related flaw impacting the rules of security groups; corrective measures released.
Nova could be prevented from applying security group policy.

Summary

Nova could be prevented from applying security group policy.

Software Description:

- nova: OpenStack Compute cloud infrastructure

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.
