    libvirt vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 13.10
    
    Summary:
    
    libvirt would allow unintended access privileges.
    
    Software Description:
    - libvirt: Libvirt virtualization toolkit
    
    Details:
    
    It was discovered that libvirt incorrectly checked privileges when the
    virConnectDomainXMLToNative API function was used. An attacker could
    possibly use this flaw to gain write privileges, contrary to expected
    behaviour.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 13.10:
      libvirt0                        1.1.1-0ubuntu8.1
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
