NanoSVG commit 239e102ec contains an incorrect numeric conversion vulnerability in nsvg__pathArcTo() when parsing SVG arc commands. A specially crafted SVG document containing extreme arc radius values can cause intermediate arc calculations to produce a NaN delta angle. The function subsequently converts this NaN value to int without validating that it is finite and representable, resulting in undefined behavior and process termination, leading to denial of service.
