    libapache2-mod-perl2 vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.10
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    
    Summary:
    
    mod_perl could be made to run programs contrary to expectations.
    
    Software Description:
    - libapache2-mod-perl2: Integration of perl with the Apache2 web server
    
    Details:
    
    Jan Ingvoldstad discovered that mod_perl incorrectly handled configuration
    options to disable being used by unprivileged users, contrary to the
    documentation. A local attacker could possibly use this issue to execute
    arbitrary Perl code.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 18.10:
      libapache2-mod-perl2            2.0.10-2ubuntu3.18.10.1
    
    Ubuntu 18.04 LTS:
      libapache2-mod-perl2            2.0.10-2ubuntu3.18.04.1
    
    Ubuntu 16.04 LTS:
      libapache2-mod-perl2            2.0.9-4ubuntu1.2
    
    Ubuntu 14.04 LTS:
      libapache2-mod-perl2            2.0.8+httpd24-r1449661-6ubuntu2.1
    
    In general, a standard system update will make all the necessary changes.
