Synopsis
========

A vulnerability in Ansible may allow local attackers to gain escalated
privileges or write arbitrary files.

Background
==========

Ansible is a radically simple IT automation platform.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-admin/ansible            < 1.9.6                    >= 1.9.6 

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

The create_script function in the lxc_container module of Ansible uses
predictable temporary file names, making it vulnerable to a symlink
attack.

Impact
======

Local attackers could write arbitrary files or gain escalated
privileges within the container.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Ansible 1.9.x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-admin/ansible-1.9.6"

All Ansible 2.0.2.x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-admin/ansible-2.0.2.0-r1"
