    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 10.04 LTS
    
    Summary:
    
    Several security issues were fixed in the kernel.
    
    Software Description:
    - linux: Linux kernel
    
    Details:
    
    Chris Evans reported an flaw in the Linux kernel's handling of iso9660
    (compact disk filesystem) images. An attacker who can mount a custom
    iso9660 image either via a CD/DVD drive or a loopback mount could cause a
    denial of service (system crash or reboot). (CVE-2014-5471)
    
    Chris Evans reported an flaw in the Linux kernel's handling of iso9660
    (compact disk filesystem) images. An attacker who can mount a custom
    iso9660 image, with a self-referential CL entry, either via a CD/DVD drive
    or a loopback mount could cause a denial of service (unkillable mount
    process). (CVE-2014-5472)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 10.04 LTS:
      linux-image-2.6.32-66-386       2.6.32-66.132
      linux-image-2.6.32-66-generic   2.6.32-66.132
      linux-image-2.6.32-66-generic-pae  2.6.32-66.132
      linux-image-2.6.32-66-ia64      2.6.32-66.132
      linux-image-2.6.32-66-lpia      2.6.32-66.132
      linux-image-2.6.32-66-powerpc   2.6.32-66.132
      linux-image-2.6.32-66-powerpc-smp  2.6.32-66.132
      linux-image-2.6.32-66-powerpc64-smp  2.6.32-66.132
      linux-image-2.6.32-66-preempt   2.6.32-66.132
      linux-image-2.6.32-66-server    2.6.32-66.132
      linux-image-2.6.32-66-sparc64   2.6.32-66.132
      linux-image-2.6.32-66-sparc64-smp  2.6.32-66.132
      linux-image-2.6.32-66-versatile  2.6.32-66.132
      linux-image-2.6.32-66-virtual   2.6.32-66.132
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
    
    ATTENTION: Due to an unavoidable ABI change the kernel updates have
    been given a new version number, which requires you to recompile and
    reinstall all third party kernel modules you might have installed. If
    you use linux-restricted-modules, you have to update that package as
    well to get modules which work with the new kernel version. Unless you
    manually uninstalled the standard kernel metapackages (e.g. linux-generic,
    linux-server, linux-powerpc), a standard system upgrade will automatically
    perform this as well.
