The remote Fedora 40 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-c393b8b2fb advisory.

  - Puma is a Ruby/Rack web server built for parallelism. Prior to versions 6.3.1 and 5.6.7, puma exhibited     incorrect behavior when parsing chunked transfer encoding bodies and zero-length Content-Length headers in     a way that allowed HTTP request smuggling. Severity of this issue is highly dependent on the nature of the     web site using puma is. This could be caused by either incorrect parsing of trailing fields in chunked     transfer encoding bodies or by parsing of blank/zero-length Content-Length headers. Both issues have been     addressed and this vulnerability has been fixed in versions 6.3.1 and 5.6.7. Users are advised to upgrade.
    There are no known workarounds for this vulnerability. (CVE-2023-40175)

  - Puma is a web server for Ruby/Rack applications built for parallelism. Prior to version 6.4.2, puma     exhibited incorrect behavior when parsing chunked transfer encoding bodies in a way that allowed HTTP     request smuggling. Fixed versions limits the size of chunk extensions. Without this limit, an attacker     could cause unbounded resource (CPU, network bandwidth) consumption. This vulnerability has been fixed in     versions 6.4.2 and 5.6.8. (CVE-2024-21647)
