A security issue affects these releases of Ubuntu and its derivatives:
o Ubuntu 18.04 LTS

Summary
Several security issues were fixed in PostgreSQL.
Software Description
o postgresql-10 - object-relational SQL database
o postgresql-9.5 - Object-relational SQL database
o postgresql-9.3 - Object-relational SQL database
Details
Andrew Krasichkov discovered that the PostgreSQL client library incorrectly
reset its internal state between connections. A remote attacker could possibly
use this issue to bypass certain client-side connection security features. This
issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2018-10915)
It was discovered that PostgreSQL incorrectly checked authorization on certain
