CVE-2023-1010Public exploit

Crash via unchecked voxel-coordinate indexing

Published Feb 24, 2023 · Updated Aug 2, 2024

Heap-based buffer overflow in jemisa vox2png 1.0 allows attackers to crash the converter by supplying a crafted .vox file. In main, voxel coordinates from the file are combined into dataIndex and used to write currentColor into pngData without bounds checking. A user must run the local command-line tool on the file; the demonstrated result is an out-of-bounds heap access followed by a segmentation fault or AddressSanitizer abort.
