NVD Description

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

OpenTelemetry-cpp is the C++ implementation of OpenTelemetry. Prior to release 1.27.0, the OTLP HTTP exporters (traces/metrics/logs) read the full HTTP response into an in-memory vector of bytes without a size cap. This is exploitable for memory exhaustion when the configured collector endpoint is attacker-controlled (or a network attacker can MITM the exporter connection). This vulnerability is fixed in opentelemetry-cpp release 1.27.0.
