Synopsis
========

A vulnerability in Ansible may allow rogue clients to execute commands
on the Ansible controller.

Background
==========

Ansible is a radically simple IT automation platform.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-admin/ansible         < 2.1.4.0_rc3           >= 2.1.4.0_rc3
                               < 2.2.1.0_rc5           >= 2.2.1.0_rc5

Description
===========

An input validation vulnerability was found in Ansible's handling of
data sent from client systems.

Impact
======

An attacker with control over a client system being managed by Ansible
and the ability to send facts back to the Ansible server could execute
arbitrary code on the Ansible server using the Ansible-server
privileges.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Ansible 2.1.x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-admin/ansible-2.1.4.0_rc3"

All Ansible 2.2.x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-admin/ansible-2.2.1.0_rc5"
