"The remote Red Hat Enterprise Linux CoreOS 4 host has a package installed that is affected by multiple vulnerabilities
as referenced in the RHSA-2024:0207 advisory.

  - OpenTelemetry-Go Contrib is a collection of third-party packages for OpenTelemetry-Go. Prior to version
    0.46.0, the grpc Unary Server Interceptor out of the box adds labels `net.peer.sock.addr` and
    `net.peer.sock.port` that have unbound cardinality. It leads to the server's potential memory exhaustion
    when many malicious requests are sent. An attacker can easily flood the peer address and port for
    requests. Version 0.46.0 contains a fix for this issue. As a workaround to stop being affected, a view
    removing the attributes can be used. The other possibility is to disable grpc metrics instrumentation by
    passing `otelgrpc.WithMeterProvider` option with `noop.NewMeterProvider`. (CVE-2023-47108)

  - A flaw was found in CRI-O that involves an experimental annotation leading to a container being
    unconfined. This may allow a pod to specify and get any amount of memory/cpu, circumventing the kubernetes
    scheduler and potentially resulting in a denial of service in the node. (CVE-2023-6476)

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