Description

An update for ansible is now available for Ansible Engine 2

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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 (2.9.4)

Bug Fix(es) :

  • CVE-2019-14904 Ansible: vulnerability in solaris_zone module via crafted solaris zone

  • CVE-2019-14905 Ansible: malicious code could craft filename in nxos_file_copy module

See: https://github.com/ansible/ansible/blob/v2.9.4/changelogs/CHANGELOG-v2 .9.rst for details on bug fixes in this release.
