FreeRDP before 3.32.0 contains a client-side heap out-of-bounds write vulnerability in general_LumaToYUV444 and general_ChromaV2ToYUV444 that allows malicious RDP servers to corrupt client memory. Attackers can send RDPGFX AVC444 or AVC444v2 frames with odd-height region rects ending at surface height to write past U/V planes, enabling heap corruption and potential code execution.
