CVE-2024-23947Network attack vector

Memory corruption via unchecked binary node index

Published May 28, 2024 · Updated Feb 13, 2025

Out-of-bounds write in libigl 2.5.0 allows remote attackers to corrupt memory when a user opens a crafted binary .msh file. In igl::MshLoader::parse_nodes, a node identifier read from the file is decremented and used to index the m_nodes vector without checking it against the allocation sized by the declared node count. Exploitation requires a downstream application built with the affected header-only library to pass the file to readMSH, and the resulting write can crash the process or corrupt its data.
