    libxml2 vulnerability
    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
    - Ubuntu 8.04 LTS
    Applications using libxml2 could be made to crash or run programs as
    your login if they opened a specially crafted file.
    Software Description:
    - libxml2: GNOME XML library
    It was discovered that libxml2 had a heap-based buffer underflow
    when parsing entities. If a user or automated system were tricked into
    processing a specially crafted XML document, applications linked against
    libxml2 could be made to crash or possibly execute arbitrary code.

    package versions:
    Ubuntu 12.10:
      libxml2                         2.8.0+dfsg1-5ubuntu2.1
    Ubuntu 12.04 LTS:
      libxml2                         2.7.8.dfsg-5.1ubuntu4.3
    Ubuntu 11.10:
      libxml2                         2.7.8.dfsg-4ubuntu0.5
    Ubuntu 10.04 LTS:
      libxml2                         2.7.6.dfsg-1ubuntu1.7
