    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.10
    - Ubuntu 19.04
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    USN-4171-1 introduced a regression in Apport.
    
    Software Description:
    - apport: automatically generate crash reports for debugging
    
    Details:
    
    USN-4171-1 fixed vulnerabilities in Apport. The update caused a regression
    in the Python Apport library. This update fixes the problem.
    
    We apologize for the inconvenience.
    
    Original advisory details:
    
     Kevin Backhouse discovered Apport would read its user-controlled settings
     file as the root user. This could be used by a local attacker to possibly
     crash Apport or have other unspecified consequences. (CVE-2019-11481)
    
     Sander Bos discovered a race-condition in Apport during core dump
     creation. This could be used by a local attacker to generate a crash report
     for a privileged process that is readable by an unprivileged user.
     (CVE-2019-11482)
    
     Sander Bos discovered Apport mishandled crash dumps originating from
     containers. This could be used by a local attacker to generate a crash
     report for a privileged process that is readable by an unprivileged user.
     (CVE-2019-11483)
    
     Sander Bos discovered Apport mishandled lock-file creation. This could be
     used by a local attacker to cause a denial of service against Apport.
     (CVE-2019-11485)
    
     Kevin Backhouse discovered Apport read various process-specific files with
     elevated privileges during crash dump generation. This could could be used
     by a local attacker to generate a crash report for a privileged process
     that is readable by an unprivileged user. (CVE-2019-15790)
