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"
