13 July 2023
PostgreSQL could be made to run code with elevated privileges.
Releases
o Ubuntu 16.04 ESM
Packages

Alexander Lakhin discovered that PostgreSQL incorrectly handled certain
CREATE privileges. An authenticated user could possibly use this issue to
execute arbitrary code as the bootstrap supervisor.

The problem can be corrected by updating your system to the following package
versions:
Ubuntu 16.04
o postgresql-9.5 – 9.5.25-0ubuntu0.16.04.1+esm4
Available with Ubuntu Pro
