    nova vulnerability
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    Nova could be made to overwrite or corrupt arbitrary files in the compute
    host file system.
    Software Description:
    - nova: OpenStack Compute cloud infrastructure
    Padraig Brady discovered that the fix for CVE-2012-3361 was incomplete and
    an authenticated user could still corrupt arbitrary files on the host
    running Nova. A remote attacker could use this to cause a denial of service
    or possibly gain privileges.
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 12.04 LTS:
      python-nova                     2012.1+stable~20120612-3ee026e-0ubuntu1.3
    Ubuntu 11.10:
      python-nova                     2011.3-0ubuntu6.10
    In general, a standard system update will make all the necessary changes.
