Ubuntu Security Notice USN-4027-1
June 20, 2019

postgresql-10, postgresql-11 vulnerability
==========================================================================

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

- Ubuntu 19.04
- Ubuntu 18.10
- Ubuntu 18.04 LTS

Summary:

PostgreSQL could be made to crash or run programs if it received specially
crafted network traffic.

Software Description:
- postgresql-11: Object-relational SQL database
- postgresql-10: Object-relational SQL database

Details:

Alexander Lakhin discovered that PostgreSQL incorrectly handled
authentication. An authenticated attacker or a rogue server could use this
issue to cause PostgreSQL to crash, resulting in a denial of service, or
possibly execute arbitrary code. The default compiler options for affected
releases should reduce the vulnerability to a denial of service.

Update instructions:

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

Ubuntu 19.04:
postgresql-11 11.4-0ubuntu0.19.04.1

Ubuntu 18.10:
postgresql-10 10.9-0ubuntu0.18.10.1

Ubuntu 18.04 LTS:
postgresql-10 10.9-0ubuntu0.18.04.1

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.
