tools/tiffcp.c in LibTIFF 4.0.7 allows remote attackers to cause a denial of service (integer underflow and heap-based buffer under-read) or possibly have unspecified other impact via a crafted TIFF image, related to READ of size 78490 and libtiff/tif_unix.c:115:23.
Weakness
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
