FreeRDP from 3.0.0 before 3.32.2 contains a file descriptor leak in parallel_process_irp_create that fails to close previous descriptors on repeated IRP_MJ_CREATE requests. A hostile RDP server with parallel-device redirection enabled can send repeated CREATE requests to exhaust the client descriptor table and crash the process.
