    libxml2 vulnerabilities
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 13.04
    - Ubuntu 12.10
    - Ubuntu 12.04 LTS
    - Ubuntu 10.04 LTS
    Several security issues were fixed in libxml2.
    Software Description:
    - libxml2: GNOME XML library
    It was discovered that libxml2 would load XML external entities by default.
    If a user or automated system were tricked into opening a specially crafted
    document, an attacker could possibly obtain access to arbitrary files or
    cause resource consumption. This issue only affected Ubuntu 10.04 LTS,
    Ubuntu 12.04 LTS, and Ubuntu 12.10. (CVE-2013-0339)
    It was discovered that libxml2 incorrectly handled documents that end
    abruptly. If a user or automated system were tricked into opening a
    specially crafted document, an attacker could possibly cause libxml2 to
    crash, resulting in a denial of service. (CVE-2013-2877)
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 13.04:
      libxml2                         2.9.0+dfsg1-4ubuntu4.2
    Ubuntu 12.10:
      libxml2                         2.8.0+dfsg1-5ubuntu2.3
    Ubuntu 12.04 LTS:
      libxml2                         2.7.8.dfsg-5.1ubuntu4.5
    Ubuntu 10.04 LTS:
      libxml2                         2.7.6.dfsg-1ubuntu1.9
    After a standard system update you need to reboot your computer to make all
    the necessary changes.
