Summary

Django is a high-level Python Web framework that encourages rapid development and a clean, pragmatic design. It focuses on automating as much as possible and adhering to the DRY (Don't Repeat Yourself) principle.
It was found that Django incorrectly handled the session store. A session could be created by anonymously accessing the django.contrib.auth.views.logout view if it was not decorated correctly with django.contrib.auth.decorators.login_required. A remote attacker could use this flaw to fill up the session store or cause other users' session records to be evicted by requesting a large number of new sessions. (CVE-2015-5963)
Red Hat would like to thank the upstream Django project for reporting this issue.
All python-django users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
