openSUSE Security Update : python-bleach (openSUSE-2021-552)

Description

This update for python-bleach fixes the following issues : - CVE-2021-23980: Fixed mutation XSS on bleach.clean with specific combinations of allowed tags (boo#1184547) Update to 3.1.5 : - replace missing ``setuptools`` dependency with ``packaging``. Thank you Benjamin Peterson. Update to 3.1.4 (boo#1168280, CVE-2020-6817) : - ``bleach.clean`` behavior parsing style attributes could result in a regular expression denial of service (ReDoS). Calls to ``bleach.clean`` with an allowed tag with an allowed ``style`` attribute were vulnerable to ReDoS. For example, ``bleach.clean(..., attributes=('a': ['style']))``. - Style attributes with dashes, or single or double quoted values are cleaned instead of passed through. update to 3.1.3 (boo#1167379, CVE-2020-6816) : - Add relative link to code of conduct. (#442) - Drop deprecated 'setup.py test' support. (#507) - Fix typo: curren -> current in tests/test_clean.py (#504) - Test on PyPy 7 - Drop test support for end of life Python 3.4 - ``bleach.clean`` behavior parsing embedded MathML and SVG content with RCDATA tags did not match browser behavior and could result in a mutation XSS. Calls to ``bleach.clean`` with ``strip=False`` and ``math`` or ``svg`` tags and one or more of the RCDATA tags ``script``, ``noscript``, ``style``, ``noframes``, ``iframe``, ``noembed``, or ``xmp`` in the allowed tags whitelist were vulnerable to a mutation XSS.
