Descriptions
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.

Cuando un usuario ejecuta "ansible-vault edit", otro usuario en la misma computadora puede leer el secreto antiguo y el nuevo, como es creado en un archivo temporal con mkstemp y el descriptor de archivo devuelto es cerrado y el método write_data es llamado para escribir el secreto existente en el archivo. Este método eliminará el archivo antes de volver a crearlo de forma no segura. Se cree todas las versiones en las derivaciones 2.7.x, 2.8.x y 2.9.x son vulnerables.
