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).
