[USN-5440-1] PostgreSQL vulnerability


========================================================================== Ubuntu Security Notice USN-5440-1 May 24, 2022
postgresql-10, postgresql-12, postgresql-13, postgresql-14 vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 22.04 LTS – Ubuntu 21.10 – Ubuntu 20.04 LTS – Ubuntu 18.04 LTS
Summary:
PostgreSQL could be made to execute commands as the superuser.
Software Description: – postgresql-14: Object-relational SQL database – postgresql-13: Object-relational SQL database – postgresql-12: Object-relational SQL database – postgresql-10: 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 LTS: postgresql-14 14.3-0ubuntu0.22.04.1
Ubuntu 21.10: postgresql-13 13.7-0ubuntu0.21.10.1
Ubuntu 20.04 LTS: postgresql-12 12.11-0ubuntu0.20.04.1
Ubuntu 18.04 LTS: 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.
