CVE-2022-38072Public exploitNetwork attack vector

Process crash via unchecked neighbor index

Published Apr 3, 2023 · Updated Feb 11, 2025

Heap overflow in ADMesh 0.98.4 and Slic3r libslic3r commit b1a5500 allows attackers to crash STL processing via a crafted file. stl_fix_normal_directions sizes norm_sw by the facet count but uses an STL-derived neighbor value as an unchecked index, causing an out-of-bounds read and a later one-byte write. Triggering requires processing an attacker-supplied STL and causes the affected process to abort; no code execution is established.
