Description
FreeRDP before 3.32.1 on Windows contains a heap out-of-bounds read in client_cli_present_gateway_message that passes a byte count as wide-character printf precision. A malicious RD Gateway can send pre-authentication consent or service messages, causing the client to read twice the buffer size, leaking heap memory or crashing.
