    expat vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 16.04 LTS
    - Ubuntu 15.10
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Expat could be made to crash or run programs as your login if it opened a
    specially crafted file.
    
    Software Description:
    - expat: XML parsing C library
    
    Details:
    
    Gustavo Grieco discovered that Expat incorrectly handled malformed XML
    data. If a user or application linked against Expat were tricked into
    opening a crafted XML file, an attacker could cause a denial of service, or
    possibly execute arbitrary code. (CVE-2016-0718)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 16.04 LTS:
      lib64expat1                     2.1.0-7ubuntu0.16.04.1
      libexpat1                       2.1.0-7ubuntu0.16.04.1
    
    Ubuntu 15.10:
      lib64expat1                     2.1.0-7ubuntu0.15.10.1
      libexpat1                       2.1.0-7ubuntu0.15.10.1
    
    Ubuntu 14.04 LTS:
      lib64expat1                     2.1.0-4ubuntu1.2
      libexpat1                       2.1.0-4ubuntu1.2
    
    Ubuntu 12.04 LTS:
      lib64expat1                     2.0.1-7.2ubuntu1.3
      libexpat1                       2.0.1-7.2ubuntu1.3
    
    After a standard system upgrade you need to restart any applications linked
    against Expat to effect the necessary changes.
