Summary
Python is an interpreted, interactive, object-oriented programming language that supports modules, classes, exceptions, high-level dynamic data types, and dynamic typing. The python27 packages provide a stable release of Python 2.7 with a number of additional utilities and database connectors for MySQL and PostgreSQL.
The following packages have been upgraded to a later upstream version: python2 (2.7.17). (BZ#1759944)
Security Fix(es):
* python-urllib3: Cross-host redirect does not remove Authorization header allow for credential exposure (CVE-2018-20060)
* python: Cookie domain check returns incorrect results (CVE-2018-20852)
* python-urllib3: CRLF injection due to not encoding the '\r\n' sequence leading to possible attack on internal service (CVE-2019-11236)
* python-urllib3: Certification mishandle when error should be thrown (CVE-2019-11324)

Critical 9.8
Exposure of Sensitive Information to an Unauthorized Actor in urllib3
urllib3 before version 1.23 does not remove the Authorization HTTP header when following a cross-origin redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the Authorization header to be exposed to unintended h…

High 7.5CVE-2018-18074 Public exploit
Insufficiently Protected Credentials in Requests
The Requests package before 2.20.0 for Python sends an HTTP Authorization header to an http URI upon receiving a same-hostname https-to-http redirect, which makes it easier for remote attackers to discover credentials by sniffing the network.
