Source: GitHub Advisory Database (reviewed) Moderate CVE-2020-14365

Packages

Ecosystem	Package	Affected	Fixed in

PyPI	ansible	>= 2.9.0a1, < 2.9.13	2.9.13

Details

As written in the advisory (Markdown source, shown as plain text).

A flaw was found in the Ansible Engine, in ansible-engine 2.8.x before 2.8.15 and ansible-engine 2.9.x before 2.9.13, when installing packages using the dnf module. GPG signatures are ignored during installation even when `disable_gpg_check` is set to `False`, which is the default behavior. This flaw leads to malicious packages being installed on the system and arbitrary code executed via package installation scripts. The highest threat from this vulnerability is to integrity and system availability.
