Red Hat Ansible Engine 2.5 RHSA-2018:2150-01 Moderate Code Execution Risk

Ansible is a simple model-driven configuration management, multi-node deployment, and remote-task execution system. Ansible works over SSH and does not require any software or daemons to be installed on remote nodes. Extension modules can be written in any language and are transferred to managed machines automatically.
The following packages have been upgraded to a newer upstream version: ansible (2.5.6)
Security fix(es):
* ansible: Inventory variables are loaded from current working directory when running ad-hoc command that can lead to code execution (CVE-2018-10874)
* ansible: ansible.cfg is being read from current working directory allowing possible code execution (CVE-2018-10875)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
This issue was discovered by Brian Coca (Red Hat), and Michael Scherer (OSAS).
Bug Fix(es):
