FreeRDP before 3.32.2 contains a heap buffer over-read vulnerability in save_png_to_buffer() that allows malicious RDP servers to leak client memory by sending 16 bpp DIB clipboard data. Attackers can offer a CF_DIB BI_BITFIELDS image that, when converted to PNG for a local application, embeds client heap bytes into the clipboard image.
