CVE-2024-24686

Memory corruption via unbounded face-comment parsing

Published May 28, 2024 · Updated Feb 13, 2025

Stack-based buffer overflow in libigl 2.5.0 allows attackers to corrupt memory via a crafted OFF file processed by readOFF. The faces-loop comment branch uses fscanf with an unbounded %[^ ] conversion to copy a line into a fixed 1,000-byte stack buffer. A consuming application must open the file and invoke readOFF; the resulting corruption can crash the process or compromise its data and execution.
