CVE-2021-3941 is fixed in 9 products on 1 platform, first by libopenexr22 2.2.0-11.1ubuntu1.9, released November 10, 2021. It is not reported as exploited. Patch Radar priority: Routine.
In ImfChromaticities.cpp routine RGBtoXYZ(), there are some division operations such as `float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;` and `chroma.green.y * (X + Z))) / d;` but the divisor is not checked for a 0 value. A specially crafted file could trigger a divide-by-zero condition which could affect the availability of programs linked with OpenEXR.
