How to fix?

Upgrade ansible-core to version 2.12.0b1 or higher.

Overview

ansible-core is an a radically simple IT automation system. It handles configuration management, application deployment, cloud provisioning, ad-hoc task execution, network automation, and multi-node orchestration. Ansible makes complex changes like zero-downtime rolling updates with load balancers easy.

Affected versions of this package are vulnerable to Race Condition. The ANSIBLE_ASYNC_DIR value defaults to ~/.ansible_async/ but is settable by the user.

When this occurs, there is a race condition on the managed machine. A malicious, low privileged account on the remote machine can pre-create /tmp/username-ansible-async and then use various attacks to access the async result data.
