LibTIFF tiffcrop.c:3609 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 version 4.4.0 is vulnerable to a buffer overflow vulnerability, which stems from a boundary error in tiffcrop at tools/tiffcrop.c:3609 when handling untrusted input. An attacker could exploit this vulnerability to cause a denial of service via a crafted tiff file.
