Name : python36 Product : Fedora 31 Version : 3.6.11 Release : 1.fc31 URL : https://www.python.org/ Summary : Version 3.6 of the Python interpreter Description : Python 3.6 package for developers.
This package exists to allow developers to test their code against an older version of Python. This is not a full Python stack and if you wish to run your applications with Python 3.6, see other distributions that support it, such as CentOS or RHEL with Software Collections or older Fedora releases.
-------------------------------------------------------------------------------- Update Information:
# Python 3.6.11 Python 3.6.11 is the latest security fix release of Python 3.6. - bpo-39073: Disallow CR or LF in email.headerregistry.Address arguments to guard against header injection attacks. - bpo-38576: Disallow control characters in hostnames in http.client, addressing CVE-2019-18348. Such potentially malicious header injection URLs now cause a InvalidURL to be raised. - bpo-39503: CVE-2020-8492: The AbstractBasicAuthHandler class of the urllib.request module uses an inefficient regular expression which can be exploited by an attacker to cause a denial of service. Fix the regex to prevent the catastrophic backtracking. Vulnerability reported by Ben Caller and Matt Schwager. Also fix a regression with `distutils.sysconfig.get_config_var('LIBPL')` value in Fedora specific patches. -------------------------------------------------------------------------------- ChangeLog:
