Summary
Red Hat Security Advisory: python27-python and python27-python-pip security update
Notes
Topic
An update for python27-python and python27-python-pip is now available for Red Hat Software Collections.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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.
Security Fix(es):
* python: urllib: Regular expression DoS in AbstractBasicAuthHandler (CVE-2021-3733)
* python: ftplib should not use the host from the PASV response (CVE-2021-4189)
* python: urllib.parse does not sanitize URLs containing ASCII newline and tabs (CVE-2022-0391)
* python: urllib: HTTP client possible infinite loop on a 100 Continue response (CVE-2021-3737)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

The issue is how the FTP client trusts the host from the PASV response by default. This flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which otherwise would not have been possible.",
