Local process crash via malformed SVG

Published Apr 29, 2026 · Updated Apr 29, 2026

Buffer overflow in GNOME librsvg 2.40.13 allows local users to crash rsvg-convert by processing a malformed SVG file. The published backtrace stops in Cairo's _fill_xrgb32_lerp_opaque_spans path while filling compositor spans; no faulty copy operation is identified. Local file processing is required, and Ubuntu disputes the librsvg attribution because the observed fault occurs in Cairo.
