+Subject: [PATCH] * libtiff/tif_dirread.c: avoid division by floating point 0
+ in TIFFReadDirEntryCheckedRational() and TIFFReadDirEntryCheckedSrational(),
+ and return 0 in that case (instead of infinity as before presumably)
+ Apparently some sanitizers do not like those divisions by zero. Fixes
