    nova vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 LTS
    - Ubuntu 13.10
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Several security issues were fixed in OpenStack Nova.
    
    Software Description:
    - nova: OpenStack Compute cloud infrastructure
    
    Details:
    
    Darragh O'Reilly discovered that OpenStack Nova did not properly set up its
    sudo configuration. If a different flaw was found in OpenStack Nova, this
    vulnerability could be used to escalate privileges. This issue only
    affected Ubuntu 13.10 and Ubuntu 14.04 LTS. (CVE-2013-1068)
    
    Bernhard M. Wiedemann and Pedraig Brady discovered that OpenStack Nova did
    not properly verify the virtual size of a QCOW2 images. A remote
    authenticated attacker could exploit this to create a denial of service via
    disk consumption. This issue did not affect Ubuntu 14.04 LTS.
    (CVE-2013-4463, CVE-2013-4469)
    
    JuanFra Rodriguez Cardoso discovered that OpenStack Nova did not enforce
    SSL connections when Nova was configured to use QPid and qpid_protocol is
    set to 'ssl'. If a remote attacker were able to perform a man-in-the-middle
    attack, this flaw could be exploited to view sensitive information. Ubuntu
    does not use QPid with Nova by default. This issue did not affect Ubuntu
    14.04 LTS. (CVE-2013-6491)
    
    Loganathan Parthipan discovered that OpenStack Nova did not properly create
    expected files during KVM live block migration. A remote authenticated
    attacker could exploit this to obtain root disk snapshot contents via
    ephemeral storage. This issue did not affect Ubuntu 14.04 LTS.
    (CVE-2013-7130)
    
    Stanislaw Pitucha discovered that OpenStack Nova did not enforce the image
    format when rescuing an instance. A remote authenticated attacker could
    exploit this to read host files. In the default installation, attackers
    would be isolated by the libvirt guest AppArmor profile. This issue only
    affected Ubuntu 13.10. (CVE-2014-0134)
    
    Mark Heckmann discovered that OpenStack Nova did not enforce RBAC policy
    when adding security group rules via the EC2 API. A remote authenticated
    user could exploit this to gain unintended access to this API. This issue
    only affected Ubuntu 13.10. (CVE-2014-0167)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 LTS:
      python-nova                     1:2014.1-0ubuntu1.2
    
    Ubuntu 13.10:
      python-nova                     1:2013.2.3-0ubuntu1.2
    
    Ubuntu 12.04 LTS:
      python-nova                     2012.1.3+stable-20130423-e52e6912-0ubuntu1.4
    
    In general, a standard system update will make all the necessary changes.
