Fedora 31: 2020-d808fdd597 Critical: Python3 DoS and Pathfix Issue

Python is an accessible, high-level, dynamically typed, interpreted programming

language, designed with an emphasis on code readability.

It includes an extensive standard library, and has a vast ecosystem of

third-party libraries.

The python3 package provides the "python3" executable: the reference

interpreter for the Python language, version 3.

The majority of its standard library is provided in the python3-libs package,

which should be installed automatically along with python3.

The remaining parts of the Python standard library are broken out into the

python3-tkinter and python3-test packages, which may need to be installed

separately.

Documentation for Python is provided in the python3-docs package.

Packages containing additional libraries for Python are generally named with

the "python3-" prefix.

Security fix for CVE-2019-20907, CVE-2020-14422. Provide a versioned

pathfix3.7.py command.
