    apport vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 ESM
    
    Summary:
    
    Apport could be made to expose sensitive information in crash reports.
    
    Software Description:
    - apport: automatically generate crash reports for debugging
    
    Details:
    
    USN-4051-1 fixed a vulnerability in apport. This update provides
    the corresponding update for Ubuntu 14.04 ESM.
    
    Original advisory details:
    
     Kevin Backhouse discovered a race-condition when reading the user's local
     Apport configuration. This could be used by a local attacker to cause
     Apport to include arbitrary files in a resulting crash report.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 ESM:
      python-apport                   2.14.1-0ubuntu3.29+esm1
      python3-apport                  2.14.1-0ubuntu3.29+esm1
    
    In general, a standard system update will make all the necessary changes.
