    libxml2 vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 ESM
    
    Summary:
    
    curl could be made to crash if it received specially crafted
    input.
    
    Software Description:
    - libxml2: GNOME XML library
    
    Details:
    
    USN-3504-1 fixed a vulnerability in libxml2. This update provides
    the corresponding update for Ubuntu 12.04 ESM.
    
    Original advisory details:
    
     Wei Lei discovered that libxml2 incorrecty handled certain parameter
     entities. An attacker could use this issue with specially constructed
     XML data to cause libxml2 to consume resources, leading to a denial of
     service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 ESM:
      libxml2                         2.7.8.dfsg-5.1ubuntu4.19
      libxml2-utils                   2.7.8.dfsg-5.1ubuntu4.19
      python-libxml2                  2.7.8.dfsg-5.1ubuntu4.19
    
    In general, a standard system update will make all the necessary
    changes.
