CVE-2026-41078: OpenTelemetry .NET has potential memory exhaustion via unbounded pooled-list sizing in Jaeger exporter conversion path

[!IMPORTANT] There is no plan to fix this issue as OpenTelemetry.Exporter.Jaeger was deprecated in 2023. It is for informational purposes only.

OpenTelemetry.Exporter.Jaeger may allow sustained memory pressure when the internal pooled-list sizing grows based on a large observed span/tag set and that enlarged size is reused for subsequent allocations. Under high-cardinality or attacker-influenced telemetry input, this can increase memory consumption and potentially cause denial of service.
