    evince update
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    Use more restrictive AppArmor policy for Evince binaries.
    Software Description:
    - evince: Document viewer
    As a security improvement, this update adjusts the AppArmor profile for the
    Evince thumbnailer to reduce access to the system and adjusts the AppArmor
    profile for Evince and Evince previewer to limit access to the DBus system
    bus. Additionally adjust the evince abstraction to disallow writes on
    parent directories of sensitive files.
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 18.04 LTS:
      evince-common                   3.28.4-0ubuntu1.2
    Ubuntu 16.04 LTS:
      evince-common                   3.18.2-1ubuntu4.5
    In general, a standard system update will make all the necessary changes.
