CVE-2021-3941

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.

This flaw is out of support scope for OpenEXR as shipped in Red Hat Enterprise Linux 6 and 7. Please see https://access.redhat.com/support/policy/updates/errata/ for more information on support scopes.
