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

- - Ubuntu 17.10
- - Ubuntu 16.04 LTS
- - Ubuntu 14.04 LTS


PostgreSQL could be made to execute arbitrary code.

Software Description:
- - postgresql-9.6: Object-relational SQL database

- - postgresql-9.3: Object-relational SQL database


It was discovered that PostgreSQL incorrectly handled certain settings.
An attacker could possibly use this issue to execute arbitrary code.

Update instructions:

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

Ubuntu 17.10:
  postgresql-9.6     9.6.8-0ubuntu0.17.10

make all the necessary changes.
