Description OSIDB Bzimport 2026-11-03 17:17:39 UTC 
FreeRDP before 3.32.2 fails to bound server-supplied target dimensions and output origin in RDPGFX MAPSURFACETOSCALEDOUTPUT PDUs, allowing malicious RDP servers to abort X11 clients. Attackers can map a surface to oversized scaled output, triggering checked UINT16 cast or freerdp_image_scale stride assertion failures that terminate the client.
