==========================================================================

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

Summary:

PostgreSQL could be made to crash or run programs if it handled specially
crafted data.

Software Description:
- postgresql-9.4: Object-relational SQL database
- postgresql-9.3: Object-relational SQL database
- postgresql-9.1: Object-relational SQL database

Details:

It was discovered that PostgreSQL incorrectly handled certain regular
expressions. A remote attacker could possibly use this issue to cause
PostgreSQL to crash, resulting in a denial of service. (CVE-2016-0773)

It was discovered that PostgreSQL incorrectly handled certain configuration
settings (GUCS) for users of PL/Java. A remote attacker could possibly use
this issue to escalate privileges. (CVE-2016-0766)

Update instructions:

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

Ubuntu 15.10:
  postgresql-9.4                  9.4.6-0ubuntu0.15.10

Ubuntu 14.04 LTS:
  postgresql-9.3                  9.3.11-0ubuntu0.14.04

Ubuntu 12.04 LTS:
  postgresql-9.1                  9.1.20-0ubuntu0.12.04

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.
