Ubuntu Security Notice USN-1466-1
June 06, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
- Ubuntu 11.10
Nova could be prevented from applying security group policy.
- nova: OpenStack Compute cloud infrastructure
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
The problem can be corrected by updating your system to the following
Ubuntu 12.04 LTS:
In general, a standard system update will make all the necessary changes.
