tools/tiffcrop.c in LibTIFF 4.0.7 allows remote attackers to cause a denial of service (heap-based buffer over-read and buffer overflow) or possibly have unspecified other impact via a crafted TIFF image, related to "READ of size 1" and libtiff/tif_fax3.c:413:13.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
