CVE-2026-42450
Published:June 24, 2026
Updated:June 29, 2026
OpenColorIO is a color management framework for visual effects and animation. Prior to version 2.5.2, "FileFormatSpi3D.cpp:163" uses "sscanf" with "%s" into 64-byte stack buffers when parsing LUT data lines. Input comes from "lineBuffer[4096]", so a crafted .spi3d file can overflow by ~4000 bytes on non-Windows. Version 2.5.2 fixes the issue.
