CVE-2021-3941
https://notcve.org/view.php?id=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. En la rutina RGBtoXYZ() del archivo ImfChromaticities.cpp, se presentan algunas operaciones de división como "float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;" y "chroma.green.y * (X + Z)) / d;" pero no es comprobado que el divisor tenga un valor 0. Un archivo especialmente diseñado podría desencadenar una condición de división por cero que podría afectar a la disponibilidad de los programas enlazados con OpenEXR • https://bugzilla.redhat.com/show_bug.cgi?id=2019789 https://lists.debian.org/debian-lts-announce/2022/12/msg00022.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I2JSMJ7HLWFPYYV7IAQZD5ZUUUN7RWBN https://security.gentoo.org/glsa/202210-31 https://www.debian.org/security/2022/dsa-5299 • CWE-369: Divide By Zero •
