August 18, 2016

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.
