CVE-2023-44709Public exploit

Application crash via unchecked SVG dimensions

Published Dec 14, 2023 · Updated Oct 8, 2024

Integer overflow in PlutoSVG commit 336c02997277a1888e6ccbbbe674551a0582e5c4 and earlier allows attackers to crash applications via crafted SVGs. plutosvg_load_from_memory passes unchecked width and height values to plutovg_surface_create, where width times height times four determines the calloc size. Processing an SVG with oversized dimensions can overflow that calculation and terminate the consuming process; arbitrary code execution remains unverified.
