Title
CairoSVG vulnerable to Exponential DoS via recursive <use> element amplification
Summary
CairoSVG is an SVG converter based on Cairo, a 2D graphics library. Prior to Kozea/CairoSVG has exponential denial of service via recursive <use> element amplification in cairosvg/defs.py. This causes CPU exhaustion from a small input.
