    libvirt vulnerabilities
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 11.04
    - Ubuntu 10.10
    - Ubuntu 10.04 LTS
    Libvirt could be made to crash or read arbitrary files on the host.
    Software Description:
    - libvirt: Libvirt virtualization toolkit
    It was discovered that libvirt did not use thread-safe error reporting. A
    remote attacker could exploit this to cause a denial of service via
    application crash. (CVE-2011-1486)
    Eric Blake discovered that libvirt had an off-by-one error which could
    be used to reopen disk probing and bypass the fix for CVE-2010-2238. A
    privileged attacker in the guest could exploit this to read arbitrary files
    on the host. This issue only affected Ubuntu 11.04. By default, guests are
    confined by an AppArmor profile which provided partial protection against
    this flaw. (CVE-2011-2178)
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 11.04:
      libvirt-bin                     0.8.8-1ubuntu6.2
      libvirt0                        0.8.8-1ubuntu6.2
    Ubuntu 10.10:
      libvirt-bin                     0.8.3-1ubuntu18
      libvirt0                        0.8.3-1ubuntu18
    Ubuntu 10.04 LTS:
      libvirt-bin                     0.7.5-5ubuntu27.13
      libvirt0                        0.7.5-5ubuntu27.13
    In general, a standard system update will make all the necessary changes.
      CVE-2011-1486, CVE-2011-2178
