LibTIFF tiffcrop.c:3724 buffer overflow vulnerability

LibTIFF is a library for reading and writing TIFF (Tagged Image File Format) files. The library contains a number of command line tools for working with TIFF files. LibTIFF suffers from a buffer overflow vulnerability, which stems from a boundary error in tiffcrop at tools/tiffcrop.c:3724 when handling untrusted input. An attacker could exploit this vulnerability to cause a denial of service via a crafted tiff file.
