RHCOS 4 : OpenShift Container Platform 4.12.48 (RHSA-2024:0489)

high Nessus Plugin ID 189868

Synopsis

The remote Red Hat CoreOS host is missing a security update for OpenShift Container Platform 4.12.48.

Description

The remote Red Hat Enterprise Linux CoreOS 4 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2024:0489 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)

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

Solution

Update the RHCOS OpenShift Container Platform 4.12.48 packages based on the guidance in RHSA-2024:0489.
