Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
LibRaw through 0.22.2 contains a heap-based out-of-bounds read in LibRaw::parseNikonMakernote() that allows attackers to read past a short ShotInfo buffer. Attackers can supply a crafted Nikon NEF/TIFF with a 5-byte ShotInfo tag declaring version 243 to crash applications decoding the image.
