Process crash via near-null read in plutovg_blend
Published Jan 23, 2025 · Updated Mar 14, 2025
Denial of service in LunaSVG 3.0.0 allows context-dependent attackers to crash an SVG-rendering process with a crafted SVG file. During rendering, SVGUseElement::render reaches Canvas::blendCanvas and plutovg_blend, where the crafted document triggers a near-null read and segmentation fault. A consuming application must render the supplied SVG; the demonstrated consequence is process termination, not data disclosure or code execution.
