Moderate: python38:3.8 and python38-devel:3.8 security update

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-psutil: Double free because of refcount mishandling (CVE-2019-18874) * python-jinja2: ReDoS vulnerability in the urlize filter (CVE-2020-28493) * python: Information disclosure via pydoc (CVE-2021-3426) * python-babel: Relative path traversal allows attacker to load arbitrary locale files and execute arbitrary code (CVE-2021-20095, CVE-2021-42771) * python: Web cache poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a semicolon in query parameters (CVE-2021-23336) * python-lxml: Missing input sanitization for formaction HTML5 attributes may lead to XSS (CVE-2021-28957) * python-ipaddress: Improper input validation of octal strings (CVE-2021-29921) * python-urllib3: ReDoS in the parsing of authority part of URL (CVE-2021-33503) * python-pip: Incorrect handling of unicode separators in git references (CVE-2021-3572) 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.
