How to fix?

Upgrade ansible to version 2.3.1.0, 2.4.0.0 or higher.

Overview

ansible is a radically simple IT automation system.

Affected versions of this package are vulnerable to Arbitrary Code Execution. It fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution.
