USN-5440-1: PostgreSQL vulnerability

Releases

• Ubuntu 22.04 LTS
• Ubuntu 21.10
• Ubuntu 20.04 LTS
• Ubuntu 18.04 ESM

Packages

• postgresql-10 - Object-relational SQL database
• postgresql-12 - Object-relational SQL database
• postgresql-13 - Object-relational SQL database
• postgresql-14 - Object-relational SQL database

Details

Alexander Lakhin discovered that PostgreSQL incorrectly handled the
security restricted operation sandbox when a privileged user is maintaining
another user's objects. An attacker having permission to create non-temp
objects can use this issue to execute arbitrary commands as the superuser.

Update instructions

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

Ubuntu 22.04

• postgresql-14 - 14.3-0ubuntu0.22.04.1

Ubuntu 21.10

• postgresql-13 - 13.7-0ubuntu0.21.10.1

Ubuntu 20.04

• postgresql-12 - 12.11-0ubuntu0.20.04.1

Ubuntu 18.04

• postgresql-10 - 10.21-0ubuntu0.18.04.1

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.
