Application crash via unchecked SVG numeric values
Published Aug 11, 2023 · Updated Oct 9, 2024
Integer overflow in Qt SVG 5.15.1, 6.0.0, 6.0.2, and 6.2 allows local users to crash applications with a crafted SVG file. qsvghandler accepts numeric values outside the normal float range, after which float-based radial-gradient rendering can perform an out-of-bounds memory access. Exploitation requires an application to process the file and user interaction; the documented consequence is an application crash.
