This security bulletin contains information about 3 secuirty vulnerabilities.

1) Information disclosure (CVE-ID: CVE-2018-10855)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to improper honor of 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.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
