"The version of etcd / cri-tools / cert-manager / coredns / cf-cli / blobfuse2 installed on the remote CBL Mariner 2.0
host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-39325
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)

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