[USN-5145-1] PostgreSQL vulnerabilities

========================================================================== 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
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
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.
