NVD Description

Note: Versions mentioned in the description apply only to the upstream freerdp-devel package and not the freerdp-devel package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
