Ubuntu Security Notice USN-3818-1
November 14, 2018

postgresql-10 vulnerability
==========================================================================

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

- - Ubuntu 18.10
- - Ubuntu 18.04 LTS

Summary:

PostgreSQL could be made to run SQL statements as the administrator.

Software Description:
- - postgresql-10: Object-relational SQL database

Details:

It was discovered that PostgreSQL incorrectly handled certain trigger
definitions when running pg_upgrade or pg_dump. A remote attacker could
possibly use this issue to execute arbitrary SQL statements with superuser
privileges.

Update instructions:

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

Ubuntu 18.10:
  postgresql-10                   10.6-0ubuntu0.18.10.1

Ubuntu 18.04 LTS:
  postgresql-10                   10.6-0ubuntu0.18.04.1

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.
