CVE-2024-23951Network attack vector

Memory corruption via unchecked ASCII element index

Published May 28, 2024 · Updated Feb 13, 2025

Out-of-bounds write in libigl 2.5.0 allows remote attackers to corrupt a consuming application's memory via a crafted ASCII .msh file. In igl::MshLoader::parse_element_field, the ASCII path subtracts one from a file-supplied element index and writes into a vector without checking its bounds. A user or automated workflow must pass the file to readMSH; the resulting memory corruption can crash the host process or permit code execution in its context.
