package/python-django: security bump to version 3.2.2
Django 3.0.x is EOL, so move to 3.2.x which is the new LTS release. For
details of the changes and update instructions, see the announcement:
https://www.djangoproject.com/weblog/2021/apr/06/django-32-released/
Fixes the following security issues:
- CVE-2021-30459 - SQL Injection via Select, Explain and Analyze forms of
the SQLPanel for Django Debug Toolbar >= 0.10.0
With Django Debug Toolbar 0.10.0 and above, attackers are able to execute
SQL by changing the raw_sql input of the SQL explain, analyze or select
forms and submitting the form. This is a high severity issue for anyone
using the toolbar in a production environment. Generally the Django Debug
Toolbar team only maintains the latest version of django-debug-toolbar,
but an exception was made because of the high severity of this issue.

- CVE-2021-31542: Potential directory-traversal via uploaded files
MultiPartParser, UploadedFile, and FieldFile allowed directory-traversal
via uploaded files with suitably crafted file names.
In order to mitigate this risk, stricter basename and path sanitation is
now applied. Specifically, empty file names and paths with dot segments
will be rejected.
This issue has low severity, according to the Django security policy.
- CVE-2021-32052: Header injection possibility since URLValidator accepted
newlines in input on Python 3.9.5+
On Python 3.9.5+, URLValidator didn't prohibit newlines and tabs. If you
used values with newlines in HTTP response, you could suffer from header
injection attacks. Django itself wasn't vulnerable because HttpResponse
prohibits newlines in HTTP headers.
Moreover, the URLField form field which uses URLValidator silently removes
newlines and tabs on Python 3.9.5+, so the possibility of newlines
entering your data only existed if you are using this validator outside of
the form fields.
This issue was introduced by the bpo-43882 fix.
