    keystone vulnerabilities
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 12.10
    - Ubuntu 12.04 LTS
    Keystone would allow unintended access to files over the network.
    Software Description:
    - keystone: OpenStack identity service
    Vijaya Erukala discovered that Keystone did not properly invalidate
    EC2-style credentials such that if credentials were removed from a tenant,
    an authenticated and authorized user using those credentials may still be
    allowed access beyond the account owner's expectations. (CVE-2012-5571)
    It was discovered that Keystone did not properly implement token
    expiration. A remote attacker could use this to continue to access an
    account that is disabled or has a changed password. This issue was
    previously fixed as CVE-2012-3426 but was reintroduced in Ubuntu 12.10.
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 12.10:
      python-keystone                 2012.2-0ubuntu1.2
    Ubuntu 12.04 LTS:
      python-keystone                 2012.1+stable~20120824-a16a0ab9-0ubuntu2.3
    In general, a standard system update will make all the necessary changes.
      CVE-2012-5563, CVE-2012-5571
