How to fix?

Upgrade RHEL:7 ansible to version 0:2.9.7-1.el7ae or higher.
This issue was patched in RHSA-2020:1541.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ansible package and not the ansible package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was found in Ansible Engine when using Ansible Vault for editing encrypted files. When a user executes "ansible-vault edit", another user on the same computer can read the old and new secret, as it is created in a temporary file with mkstemp and the returned file descriptor is closed and the method write_data is called to write the existing secret in the file. This method will delete the file before recreating it insecurely. All versions in 2.7.x, 2.8.x and 2.9.x branches are believed to be vulnerable.
