Detail

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.

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"
