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.
