"John Heasman discovered a local privilege escalation in the PostgreSQL
server. Any user could use the LOAD extension to load any shared
library into the PostgreSQL server; the library's initialisation
function was then executed with the permissions of the server.

Now the use of LOAD is restricted to the database superuser (usually
'postgres').

Note: Since there is no way for normal database users to create
arbitrary files, this vulnerability is not exploitable remotely, e. g.
by uploading a shared library in the form of a Binary Large Object
(BLOB) to a public web server.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
