"The version of containerd / cri-tools / docker-buildx / docker-compose / moby-containerd-cc installed on the remote
Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the
CVE-2023-47108 advisory.

  - OpenTelemetry-Go Contrib is a collection of third-party packages for OpenTelemetry-Go. Starting in version
    0.37.0 and 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`.
