Ubuntu 18.04 LTS : PostgreSQL vulnerability (USN-3818-1)

critical Nessus Plugin ID 118966

Synopsis

The remote Ubuntu host is missing a security update.

Description

It was discovered that PostgreSQL incorrectly handled certain trigger definitions when running pg_upgrade or pg_dump. A remote attacker could possibly use this issue to execute arbitrary SQL statements with superuser privileges.

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.

Solution
