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"

References
==========
