Technical details
The vulnerability is a heap out-of-bounds read in client_cli_present_gateway_message() on Windows, where a byte count is incorrectly passed as a wide-character printf precision. MSVC's %.*S format specifier interprets precision as a WCHAR count, causing it to read double the intended buffer size. The flaw occurs during RD Gateway tunnel setup when processing pre-authentication consent or service messages. A malicious gateway can leak heap memory or trigger a denial of service.
