Summary

OpenEXR security update

Details

OpenEXR is a high dynamic-range (HDR) image file format originally developed by Industrial Light & Magic for use in computer imaging applications.

Security Fix(es):

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.(CVE-2021-3941)

Severity

6.5 (Medium)


                    
                      CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H
