    swift vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 15.04
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Several security issues were fixed in Swift.
    
    Software Description:
    - swift: OpenStack distributed virtual object store
    
    Details:
    
    Rajaneesh Singh discovered Swift does not properly enforce metadata
    limits. An attacker could abuse this issue to store more metadata than
    allowed by policy. (CVE-2014-7960)
    
    Clay Gerrard discovered Swift allowed users to delete the latest version
    of object regardless of object permissions when allow_version is
    configured. An attacker could use this issue to delete objects.
    (CVE-2015-1856)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.04:
      swift                           2.2.2-0ubuntu1.3
    
    Ubuntu 14.04 LTS:
      swift                           1.13.1-0ubuntu1.2
    
    Ubuntu 12.04 LTS:
      swift                           1.4.8-0ubuntu2.5
    
    After a standard system update you need to restart swift to make
    all the necessary changes.
