USN-5145-1: PostgreSQL vulnerabilities
11 November 2021
PostgreSQL could allow unintended access to network services.
Releases
o Ubuntu 21.10
o Ubuntu 21.04
o Ubuntu 20.04 LTS
o Ubuntu 18.04 LTS
Packages
o postgresql-10 - Object-relational SQL database
o postgresql-12 - 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
o postgresql-13 - 13.5-0ubuntu0.21.10.1
Ubuntu 21.04
o postgresql-13 - 13.5-0ubuntu0.21.04.1
Ubuntu 20.04
o postgresql-12 - 12.9-0ubuntu0.20.04.1
Ubuntu 18.04
o 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.
