Heap-based buffer overflow in the horizontalDifference8 function in tif_pixarlog.c in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted TIFF image to tiffcp.
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.
