K000138255 : Go OpenTelemetry Contrib vulnerability CVE-2023-47108

Security Advisory Description

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)
