Mageia 7 Security Update: MGASA-2020-0249 Critical Fix for Python-Typed-Ast

Advisory text to describe the update. Wrap lines at ~75 chars. Updated python-typed-ast package fixes security vulnerabilities:
typed_ast 1.3.0 and 1.3.1 has a handle_keywordonly_args out-of-bounds read. An attacker with the ability to cause a Python interpreter to parse Python source (but not necessarily execute it) may be able to crash the interpreter process. This could be a concern, for example, in a web-based service that parses (but does not execute) Python code (CVE-2019-19274).
