Fedora 29: 2018:9006b64e41 Critical: Python Marshmallow Information Leak

Marshmallow is a framework-agnostic library for converting complex datatypes,

such as objects, to and from primitive Python datatypes.

Marshmallow schemas can be used to:

* Validate input data.

* Deserialize input data to app-level objects.

* Serialize app-level objects to primitive Python types. The serialized objects

can then be rendered to standard formats such as JSON for use in an HTTP API.
