What to do
AI-suggested
Until a fix is available, avoid processing untrusted SVG files with extremely large stroke-width values to reduce risk.
Description
NanoSVG contains a numeric conversion vulnerability in the nsvg__curveDivs() function during SVG stroke rasterization. A specially crafted SVG with an extremely large stroke-width can cause floating-point rounding to zero, leading to an infinite subdivision angle. This infinite value is converted to an integer without validation, causing undefined behavior and process termination, resulting in denial of service.
