Summary: PyYAML insecurely deserializes YAML strings leading to arbitrary code execution

Details: In PyYAML before 5.1, the `yaml.load()` API could execute arbitrary code. In other words, `yaml.safe_load` is not used. This was intended to be fixed in 4.1, but due to [breaking changes](https://github.com/yaml/pyyaml/issues/192#issuecomment-401491470), 4.1 was yanked and 5.1 [contains](https://github.com/yaml/pyyaml/issues/207#issuecomment-472520007) the patch for CVE-2017-18342.
