Division by zero vulnerability was found in fpAcc function in tif_predict.c in tiff2rgba, allowing attacker to cause a denial of service via a crafted TIFF image.
377 fpAcc(TIFF* tif, uint8* cp0, tmsize_t cc)
379 tmsize_t stride = PredictorState(tif)->stride;
380 uint32 bps = tif->tif_dir.td_bitspersample / 8;
381 tmsize_t wc = cc / bps;
382 tmsize_t count = cc;
383 uint8 *cp = (uint8 *) cp0;
384 uint8 *tmp = (uint8 *)_TIFFmalloc(cc);
