Detail

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

- Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS

Summary:

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

Details:

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. (CVE-2016-5423)

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.
