    qemu-kvm vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.04 LTS
    
    Summary:
    
    QEMU could be made to overwrite files as the administrator, or expose
    sensitive information.
    
    Software Description:
    - qemu-kvm: Machine emulator and virtualizer
    
    Details:
    
    It was discovered that QEMU incorrectly handled temporary files when
    creating a snapshot. A local attacker could use this flaw to possibly
    overwrite files with root privilege, or obtain sensitive information from
    the guest.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      qemu-kvm                        1.0+noroms-0ubuntu14.1
    
    Ubuntu 11.10:
      qemu-kvm                        0.14.1+noroms-0ubuntu6.4
    
    Ubuntu 11.04:
      qemu-kvm                        0.14.0+noroms-0ubuntu4.6
    
    Ubuntu 10.04 LTS:
      qemu-kvm                        0.12.3+noroms-0ubuntu9.19
    
    In general, a standard system update will make all the necessary changes.
