NVD Description
Note: Versions mentioned in the description apply only to the upstream opencolorio package and not the opencolorio package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
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.
