Doc Text:
A flaw was found in FreeRDP. On Windows builds, client_cli_present_gateway_message passes a byte count as wide-character printf precision when printing RD Gateway consent or service messages. A malicious RD Gateway can send crafted pre-authentication messages, causing the client to read beyond the buffer and potentially leak heap memory or crash. This issue affects FreeRDP before 3.32.1 on Windows.

Description OSIDB Bzimport 2026-10-21 00:58:30 UTC
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.
