"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2015:1894 advisory.

    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)

    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)

    Red Hat would like to thank the upstream Django project for reporting these
    issues. Upstream acknowledges Lin Hua Cheng as the original reporter of
    CVE-2015-5964.

    All python-django users are advised to upgrade to these updated packages,
    which contain backported patches to correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
