    postgresql-9.3, postgresql-9.5, postgresql-9.6 vulnerabilities

    A security issue affects these releases of Ubuntu and its derivatives:

    • Ubuntu 17.10
    • Ubuntu 17.04
    • Ubuntu 16.04 LTS
    • Ubuntu 14.04 LTS

    Several security issues were fixed in PostgreSQL.

    Software description

    • postgresql-9.3 - Object-relational SQL database
    • postgresql-9.5 - Object-relational SQL database
    • postgresql-9.6 - Object-relational SQL database

    David Rowley discovered that PostgreSQL incorrectly handled memory when
    processing certain JSON functions. A remote attacker could possibly use
    this issue to obtain sensitive information. (CVE-2017-15098)

    Dean Rasheed discovered that PostgreSQL incorrectly enforced SELECT
    privileges when processing INSERT ... ON CONFLICT DO UPDATE commands. A
    remote attacker could possibly use this issue to obtain sensitive
    information. This issue only affected Ubuntu 16.04 LTS, Ubuntu 17.04 and
    Ubuntu 17.10.

    Update instructions

    The problem can be corrected by updating your system to the following package version:

    Ubuntu 17.10:
    postgresql-9.6 9.6.6-0ubuntu0.17.10
    Ubuntu 17.04:
    postgresql-9.6 9.6.6-0ubuntu0.17.04
    Ubuntu 16.04 LTS:
    postgresql-9.5 9.5.10-0ubuntu0.16.04
    Ubuntu 14.04 LTS:
    postgresql-9.3 9.3.20-0ubuntu0.14.04

    To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

    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.
