FreeRDP from 3.0.0 before 3.32.0 contains an out-of-bounds read vulnerability in the Windows RAIL client that allows malicious RDP servers to trigger heap over-reads by sending non-NUL-terminated window titles. Attackers can send a full-length WINDOW_ORDER_FIELD_TITLE update that wf_rail_window_common passes to SetWindowTextW, corrupting titles or crashing the client.
