* python-jinja2: ReDoS vulnerability in the urlize filter (CVE-2020-28493)

* python-babel: Relative path traversal allows attacker to load arbitrary locale files and execute arbitrary code (CVE-2021-20095, CVE-2021-42771)

* python-pygments: Infinite loop in SML lexer may lead to DoS (CVE-2021-20270)

* 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-pygments: ReDoS in multiple lexers (CVE-2021-27291)

* python-lxml: Missing input sanitization for formaction HTML5 attributes may lead to XSS (CVE-2021-28957)
