    Ubuntu Security Notice USN-2389-1
    October 27, 2014
    
    libxml2 vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    - Ubuntu 10.04 LTS
    
    Summary:
    
    libxml2 could be made to consume resources if it processed a specially
    crafted file.
    
    Software Description:
    - libxml2: GNOME XML library
    
    Details:
    
    It was discovered that libxml2 would incorrectly perform entity
    substitution even when requested not to. If a user or automated system were
    tricked into opening a specially crafted document, an attacker could
    possibly cause resource consumption, resulting in a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 LTS:
      libxml2                         2.9.1+dfsg1-3ubuntu4.4
    
    Ubuntu 12.04 LTS:
      libxml2                         2.7.8.dfsg-5.1ubuntu4.11
    
    Ubuntu 10.04 LTS:
      libxml2                         2.7.6.dfsg-1ubuntu1.15
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
