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)
* python: email.utils.parseaddr wrongly parses email addresses (CVE-2019-16056)
* python-requests: Redirect from HTTPS to HTTP does not remove Authorization header (CVE-2018-18074)

http.cookiejar.DefaultPolicy.domain_return_ok in Lib/http/cookiejar.py in Python before 3.7.3 does not correctly validate the domain: it can be tricked into sending existing cookies to the wrong server. An attacker may abuse this flaw by using a server with a hostname that has another valid hostname as a suffix (e.g., pythonicexample.com to steal cookies for example.com). When a program uses http.cookiejar.DefaultPolicy and tries to do an HTTP connection to an attacker-controlled server, existing cookies can be leaked to the attacker. This affects 2.x through 2.7.16, 3.x before 3.4.10, 3.5.x before 3.5.7, 3.6.x before 3.6.9, and 3.7.x before 3.7.3.
