iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a crafted TIFF input can trigger Undefined Behavior (UB) due to division by zero in the TIFF handling code paths used by iccTiffDump. This issue has been patched in version 2.3.1.6.
