Ubuntu Security Notice USN-5145-1
November 11, 2021

postgresql-10, postgresql-12, postgresql-13 vulnerabilities
==========================================================================

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

- Ubuntu 21.10
- Ubuntu 21.04
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

PostgreSQL could allow unintended access to network services.

Software Description:
- postgresql-13: Object-relational SQL database
- postgresql-12: Object-relational SQL database
- postgresql-10: Object-relational SQL database

Details:

Jacob Champion discovered that PostgreSQL incorrectly handled SSL
certificate verification and encryption. A remote attacker could possibly
use this issue to inject arbitrary SQL queries when a connection is first
established.

Update instructions:

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

Ubuntu 21.10:
  postgresql-13                   13.5-0ubuntu0.21.10.1

Ubuntu 21.04:
  postgresql-13                   13.5-0ubuntu0.21.04.1

Ubuntu 20.04 LTS:
  postgresql-12                   12.9-0ubuntu0.20.04.1

Ubuntu 18.04 LTS:
  postgresql-10                   10.19-0ubuntu0.18.04.1

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.
