How to fix?

Upgrade Debian:9 postgresql-9.6 to version 9.6.10-0+deb9u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-9.6 package and not the postgresql-9.6 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

It was discovered that PostgreSQL versions before 10.5, 9.6.10, 9.5.14, 9.4.19, and 9.3.24 failed to properly check authorization on certain statements involved with "INSERT ... ON CONFLICT DO UPDATE". An attacker with "CREATE TABLE" privileges could exploit this to read arbitrary bytes server memory. If the attacker also had certain "INSERT" and limited "UPDATE" privileges to a particular table, they could exploit this to update other columns in the same table.
