CWE: CWE-78 \u2014 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.

Code:
render_pixbuf_size_prepared_cb (GdkPixbufLoader *loader,
				gint             width,
				gint             height,
				gpointer         data)
{
	double *scale = data;
	int w = (width  * (*scale) + 0.5);
	int h = (height * (*scale) + 0.5);

	gdk_pixbuf_loader_set_size (loader, w, h);
}
