Does this matter?

Lower severity and a low EPSS score (0.88%). Track it; it rarely justifies an emergency change on its own.

Description

An integer overflow could occur when OpenEXR processes a crafted file on systems where size_t < 64 bits. This could cause an invalid bytesPerLine and maxBytesPerLine value, which could lead to problems with application stability or lead to other attack paths.
