    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.10
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 10.04 LTS
    
    Summary:
    
    QEMU could be made to crash or run programs if it received specially
    crafted network traffic.
    
    Software Description:
    - qemu-kvm: Machine emulator and virtualizer
    
    Details:
    
    It was discovered that QEMU incorrectly handled certain e1000 packet sizes.
    In certain environments, an attacker may use this flaw in combination with
    large packets to cause a denial of service or execute arbitrary code in the
    guest.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.10:
      qemu-kvm                        1.2.0+noroms-0ubuntu2.12.10.2
    
    Ubuntu 12.04 LTS:
      qemu-kvm                        1.0+noroms-0ubuntu14.7
    
    Ubuntu 11.10:
      qemu-kvm                        0.14.1+noroms-0ubuntu6.6
    
    Ubuntu 10.04 LTS:
      qemu-kvm                        0.12.3+noroms-0ubuntu9.21
    
    After a standard system update you need to restart your virtual machines to
    make all the necessary changes.
