CVE-2019-3498: Content spoofing possibility in the default 404 page
An attacker could craft a malicious URL that could make spoofed content appear
on the default page generated by the django.views.defaults.page_not_found()
The URL path is no longer displayed in the default 404 template and the
request_path context variable is now quoted to fix the issue for custom
templates that use the path.
