It was found that certain Django functions would, in certain circumstances, create empty sessions. 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-2015-5964 python-django: Denial-of-service possibility in logout() view by filling session store
Following issue was reported in Django:
In CVE-2015-5963, the ``django.contrib.sessions.middleware.SessionMiddleware`` has been modified to no longer create empty session records.
Additionally, on the 1.4 and 1.7 series only, the ``contrib.sessions.backends.base.SessionBase.flush()`` and ``cache_db.SessionStore.flush()`` methods have been modified to avoid creating a new empty session.
This modification of 1.4 and 1.7 series got CVE-2015-5964.
Previously, a session could be created when anonymously accessing the ``django.contrib.auth.views.logout`` view (provided it wasn't decorated with ``django.contrib.auth.decorators.login_required`` as done in the admin). This could allow an attacker
