"The remote Debian 11 / 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dsa-5465 advisory.

  - In Django 3.2 before 3.2.17, 4.0 before 4.0.9, and 4.1 before 4.1.6, the parsed values of Accept-Language
    headers are cached in order to avoid repetitive parsing. This leads to a potential denial-of-service
    vector via excessive memory usage if the raw value of Accept-Language headers is very large.
    (CVE-2023-23969)

  - An issue was discovered in the Multipart Request Parser in Django 3.2 before 3.2.18, 4.0 before 4.0.10,
    and 4.1 before 4.1.7. Passing certain inputs (e.g., an excessive number of parts) to multipart forms could
    result in too many open files or memory exhaustion, and provided a potential vector for a denial-of-
    service attack. (CVE-2023-24580)

  - In Django 3.2 before 3.2.19, 4.x before 4.1.9, and 4.2 before 4.2.1, it was possible to bypass validation
    when using one form field to upload multiple files. This multiple upload has never been supported by
    forms.FileField or forms.ImageField (only the last uploaded file was validated). However, Django's
    Uploading multiple files documentation suggested otherwise. (CVE-2023-31047)

  - In Django 3.2 before 3.2.20, 4 before 4.1.10, and 4.2 before 4.2.3, EmailValidator and URLValidator are
    subject to a potential ReDoS (regular expression denial of service) attack via a very large number of
    domain name labels of emails and URLs. (CVE-2023-36053)

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