    postgresql-9.1, postgresql-9.3, postgresql-9.5 vulnerabilities
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    Several security issues were fixed in PostgreSQL.
    Software Description:
    - postgresql-9.5: object-relational SQL database
    - postgresql-9.3: Object-relational SQL database
    - postgresql-9.1: Object-relational SQL database
    Heikki Linnakangas discovered that PostgreSQL incorrectly handled certain
    nested CASE/WHEN expressions. A remote attacker could possibly use this
    issue to cause PostgreSQL to crash, resulting in a denial of service.
    Nathan Bossart discovered that PostgreSQL incorrectly handled special
    characters in database and role names. A remote attacker could possibly use
    this issue to escalate privileges. (CVE-2016-5424)
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 16.04 LTS:
      postgresql-9.5                  9.5.4-0ubuntu0.16.04
    Ubuntu 14.04 LTS:
      postgresql-9.3                  9.3.14-0ubuntu0.14.04
    Ubuntu 12.04 LTS:
      postgresql-9.1                  9.1.23-0ubuntu0.12.04
    This update uses a new upstream release, which includes additional bug
    fixes. After a standard system update you need to restart PostgreSQL to
    make all the necessary changes.
