   FreeRDP from 3.0.0 before 3.32.0 contains a heap out-of-bounds read vulnerability that allows a malicious RD Gateway to crash clients by sending mismatched message lengths. Attackers controlling the gateway can set MsgBytes far larger than the NDR string ActualCount in consent or service messages, causing UTF-8 conversion to read past the stream allocation and disrupt client availability.
