CVE-2021-3941 Information

Description

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.
