    nova vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 LTS
    
    Summary:
    
    OpenStack Nova could be made to expose sensitive information over the
    network.
    
    Software Description:
    - nova: OpenStack Compute cloud infrastructure
    
    Details:
    
    Alex Gaynor discovered that OpenStack Nova would sometimes respond with
    variable times when comparing authentication tokens. If nova were
    configured to proxy metadata requests via Neutron, a remote authenticated
    attacker could exploit this to conduct timing attacks and ascertain
    configuration details of another instance.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 LTS:
      python-nova                     1:2014.1.2-0ubuntu1.1
    
    In general, a standard system update will make all the necessary changes.
