As explained on issue #453 the use of the yaml.load function allows the execution of arbitrary python commands what is quite dangerous and discouraged, the problem can be solved by simply using the function safe_load instead.
In additional, two tests were added to ensure that safe_load is working as expected by properly loading valid yaml files and avoiding the execution of unstrusted commands.
Solves issue #453.
