Description
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::TlmPacketizer TlmRecv_handler fixed-slot copy TlmRecv_handler copies val.getSize bytes into entry.channelSize storage without confirming that the runtime value fits. When a telemetry update for a configured channel carries a serialized value larger than that channel fixed slot, the copy overwrites adjacent channel fields and causes corrupted packetized telemetry to be emitted. This issue is fixed in version 4.3.0.
