An update that fixes three vulnerabilities is now available.
Description:
This update for ansible fixes the following issues:
Ansible was updated to ansible 2.4.6.0.
The full release notes can be found on:
https://github.com/ansible/ansible/blob/stable-2.4/CHANGELOG.md
Security issues fixed:
- CVE-2018-10875: ansible.cfg is read from the current working directory
which can be altered to make it point to a plugin or a module path under
the control of an attacker, thus allowing the attacker to execute
arbitrary code. (bsc#1099808)
- CVE-2018-10874: It was found that inventory variables are loaded from
current working directory when running ad-hoc command which are under
attacker's control, allowing to run arbitrary code as a result.
(bsc#1099805)
- CVE-2018-10855: Ansible did not honor the no_log task flag for failed
tasks. When the no_log flag has been used to protect sensitive data
passed to a task from being logged, and that task does not run
successfully, Ansible will expose sensitive data in log files and on the
terminal of the user running Ansible. (bsc#1097775)
