Doc Text:
A flaw was found in FreeRDP. A malicious Remote Desktop Protocol (RDP) server can exploit this issue by sending a specially crafted Remote Applications Integrated Locally (RAIL) window title update that lacks proper null termination. When the Windows client processes the update, it reads past the allocated memory buffer, potentially leading to a Denial of Service (DoS) by crashing the client application or causing limited information disclosure.

Description OSIDB Bzimport 2026-10-16 01:41:30 UTC
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.
