    This could cause an invalid bytesPerLine and maxBytesPerLine value, which could lead to problems with     application stability or lead to other attack paths. (CVE-2021-3933)

  - 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)

  - OpenEXR 3.1.x before 3.1.4 has a heap-based buffer overflow in Imf_3_1::LineCompositeTask::execute (called     from IlmThread_3_1::NullThreadPoolProvider::addTask and IlmThread_3_1::ThreadPool::addGlobalTask). NOTE:
