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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.
