The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2023-13053 advisory.

  - A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive     server resource consumption. While the total number of requests is bounded by the     http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create     a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound     the number of simultaneously executing handler goroutines to the stream concurrency limit     (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client     has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows     too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2     for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per     HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the     Server.MaxConcurrentStreams setting and the ConfigureServer function. (CVE-2023-39325)

  - The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation     can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)

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