From 1.36.0 to 1.40.0, multi-value baggage: header extraction parses each header field-value independently and aggregates members across values. This allows an attacker to amplify cpu and allocations by sending many baggage: header lines, even when each individual value is within the 8192-byte per-value parse limit. This vulnerability is fixed in 1.41.0.</p> <p><strong>Affected:</strong> open-telemetry opentelemetry-go, Red Hat Cert Manager support for Red Hat OpenShift release 1.19, Red Hat Cluster Observability Operator 1.5.0, Red Hat Logging Subsystem for Red Hat OpenShift 6.6, Red Hat multicluster engine for Kubernetes 2.11, Red Hat multicluster engine for Kubernetes 2.8, Red Hat cert-manager Operator for Red Hat OpenShift, Red Hat Multicluster Engine for Kubernetes, Red Hat Advanced Cluster Management for Kubernetes 2</p> <p>OpenTelemetry-Go is the Go implementation of OpenTelemetry.
