3. Description:

Python is an interpreted, interactive, object-oriented programming
language, which includes modules, classes, exceptions, very high level
dynamic data types and dynamic typing. Python supports interfaces to many
system calls and libraries, as well as to various windowing systems. This
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.

Security Fix(es):

* python: Cookie domain check returns incorrect results (CVE-2018-20852)

* python: email.utils.parseaddr wrongly parses email addresses
(CVE-2019-16056)
