    USN-4049-1 fixed a vulnerability in GLib. The update introduced a regression
    in Ubuntu 16.04 LTS causing a possibly memory leak. This update fixes the problem.

     restricting permissions. An attacker could possibly use this issue to access
     sensitive information.

    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 16.04 LTS:
      libglib2.0-0                    2.48.2-0ubuntu4.4
      libglib2.0-bin                  2.48.2-0ubuntu4.4
