FreeBSD : ansible -- Input validation flaw in jinja2 templating system (15a04b9f-47cb-11e7-a853-001fbc0f280f)

critical Nessus Plugin ID 100610

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

RedHat security team reports :

An input validation flaw was found in Ansible, where 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, result in code execution.

Solution

Update the affected package.
