USN-6656-1: PostgreSQL vulnerability

Releases

• Ubuntu 23.10
• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS

Packages

• postgresql-12 - Object-relational SQL database
• postgresql-14 - Object-relational SQL database
• postgresql-15 - Object-relational SQL database

Details

It was discovered that PostgreSQL incorrectly handled dropping privileges
when handling REFRESH MATERIALIZED VIEW CONCURRENTLY commands. If a user or
automatic system were tricked into running a specially crafted command, a
remote attacker could possibly use this issue to execute arbitrary SQL
functions.

Update instructions

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

Ubuntu 23.10

• postgresql-15 - 15.6-0ubuntu0.23.10.1
• postgresql-client-15 - 15.6-0ubuntu0.23.10.1

Ubuntu 22.04

• postgresql-14 - 14.11-0ubuntu0.22.04.1
• postgresql-client-14 - 14.11-0ubuntu0.22.04.1

Ubuntu 20.04

• postgresql-12 - 12.18-0ubuntu0.20.04.1
• postgresql-client-12 - 12.18-0ubuntu0.20.04.1

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.
