The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:2101 advisory.
python-future: remote attackers can cause denial of service via crafted Set-Cookie header from malicious web server (CVE-2022-40899)
python-django: Potential denial-of-service via Accept-Language headers (CVE-2023-23969)
python-django: Potential denial-of-service vulnerability in file uploads (CVE-2023-24580)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
