The remote Fedora 40 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2023-a1b28cf117 advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.

- An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server
connections contain a cache of HTTP header keys sent by the client. While the total number of entries in
this cache is capped, an attacker sending very large keys can cause the server to allocate approximately
64 MiB per open connection. (CVE-2022-41717)
