vulnerabilities as referenced in the 8e6f684b-f333-11ee-a573-84a93843eb75 advisory.

  - HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject
    malicious response headers into backend applications to cause an HTTP desynchronization attack. Users are
    recommended to upgrade to version 2.4.59, which fixes this issue. (CVE-2024-24795)

  - HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an
    informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.
    (CVE-2024-27316)

  - The Apache httpd project reports: HTTP/2 DoS by memory exhaustion on endless continuation frames HTTP
    Response Splitting in multiple modules (CVE-2024-38709)

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