NVD Description

Note: Versions mentioned in the description apply only to the upstream kubernetes-reflector package and not the kubernetes-reflector package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

OpenTelemetry dotnet is a dotnet telemetry framework. From 1.13.1 to before 1.15.2, When exporting telemetry over gRPC using the OpenTelemetry Protocol (OTLP), the exporter may parse a server-provided grpc-status-details-bin trailer during retry handling. Prior to the fix, a malformed trailer could encode an extremely large length-delimited protobuf field which was used directly for allocation, allowing excessive memory allocation and potential denial of service (DoS). This vulnerability is fixed in 1.15.2.
