==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
Summary:
PostgreSQL could be made to run programs when creating or updating
extensions.
Software Description:
- postgresql-14: Object-relational SQL database
- postgresql-12: Object-relational SQL database
- postgresql-10: Object-relational SQL database
Details:
Sven Klemm discovered that PostgreSQL incorrectly handled extensions. An
attacker could possibly use this issue to execute arbitrary code when
extensions are created or updated.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS:

make all the necessary changes.
