Package: largetifftools
Version: 1.4.1-1
Dear authors,
There exists a potential division by zero in project largetifftools
In computeMaxPieceMemorySize function in tiffmakemosaic.c,
678 *hnpieces = (inimagewidth+outpiecewidth-1) /
outpiecewidth;679 *vnpieces = (inimagelength+outpiecelength-1) /
outpiecelength;
When an arbitrary input is given in makeMosaicFromTIFFFile function
as follow:
739 TIFFGetField(in, TIFFTAG_IMAGEWIDTH, &inimagewidth); 740
TIFFGetField(in, TIFFTAG_IMAGELENGTH, &inimagelength);
Possible fix would be checking if the denominators are not zero.
For example, adding the following if-guard at computeMaxPieceMemorySize
function
if (outpiecewidth == 0 || outpiecelength) {
fprintf(stderr, "division-by-zero at ...", ...);
return;
}
Thank you
Best regards
Changgong Lee
