FreeRDP before 3.32.2 X11 Client Abort via RDPGFX Scaled Output Geometry

Özet

Türkçe özeti yalnızca kritik ve yüksek önemdeki açıklar için hazırlıyoruz. Bu açık için kaynağın kendi açıklamasını gösteriyoruz.

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.
