Description

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.

A flaw was found in the Django session backends whereby an
unauthenticated attacker could cause session records to be created in
the configured session store, leading to a Denial of Service.
(CVE-2015-5143)

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 these issues.
