    apport vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.04
    - Ubuntu 18.10
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    Apport could be made to expose sensitive information in crash reports.
    
    Software Description:
    - apport: automatically generate crash reports for debugging
    
    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.

    package versions:
