Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5765-1 advisory.

 A remote attacker could possibly use this issue to inject arbitrary SQL queries when a connection is first established.
