FreeRDP from 3.0.0 before 3.32.2 contains an uncontrolled resource allocation vulnerability that allows malicious RDP servers to force large client allocations through the DRDYNVC DATA_FIRST Length field. Attackers can declare lengths up to 4,294,967,295 bytes on running dynamic channels, causing StreamPool_Take to reserve memory before body validation and exhaust client memory.
