CVE-2022-2951

Code execution via unchecked H3D buffer index

Published Dec 13, 2022 · Updated Apr 16, 2025

Improper array-index validation in Altair HyperView Player 2021.1.0.27 and earlier allows attackers to execute code via a crafted H3D file. An untrusted DWORD extracted while processing the file is used as a buffer-write index without adequate bounds validation, causing memory corruption. Exploitation requires user interaction to open the file or visit a page containing it, after which code runs in the affected process context.
