CVE-2023-43665:
In Django 3.2 before 3.2.22, 4.1 before 4.1.12, and 4.2 before 4.2.6, the
django.utils.text.Truncator chars() and words() methods (when used with
html=True) are subject to a potential DoS (denial of service) attack via
certain inputs with very long, potentially malformed HTML text. The chars()
and words() methods are used to implement the truncatechars_html and
truncatewords_html template filters, which are thus also vulnerable.
NOTE: this issue exists because of an incomplete fix for CVE-2019-14232.
CVE-2023-46695:
An issue was discovered in Django 3.2 before 3.2.23, 4.1 before 4.1.13, and
4.2 before 4.2.7. The NFKC normalization is slow on Windows. As a consequence,
django.contrib.auth.forms.UsernameField is subject to a potential DoS (denial of
service) attack via certain inputs with a very large number of Unicode characters.

In Django 3.2 before 3.2.20, 4 before 4.1.10, and 4.2 before 4.2.3,
EmailValidator and URLValidator are subject to a potential ReDoS
(regular expression denial of service) attack via a very large
number of domain name labels of emails and URLs.
Since, there is no ptest available for python3-django so have not
tested the patch changes at runtime.

In Django 3.2 before 3.2.19, 4.x before 4.1.9, and 4.2 before 4.2.1,
it was possible to bypass validation when using one form field to
upload multiple files. This multiple upload has never been supported
by forms.FileField or forms.ImageField (only the last uploaded file was
validated). However, Django's "Uploading multiple files" documentation
suggested otherwise.
Since, there is no ptest available for python3-django so have not tested
