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 backend, which could allow an
unauthenticated attacker to create session records in the configured
session store, causing a denial of service by filling up the session store.

Red Hat would like to thank the upstream Django project for reporting
