Date: July 20, 2016
Bugs: #578814
ID: 201607-14
– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –
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”
