    libxml2 vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 17.10
    - Ubuntu 17.04
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    
    Summary:
    
    libxml2 could be made to crash if it opened a specially crafted
    file.
    
    Software Description:
    - libxml2: GNOME XML library
    
    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.
