openSUSE Leap 15.2: 2021:0552-1 Important: Python-Bleach XSS Fix

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)
