LibTIFF 4.4.0 has an out-of-bounds write in TIFFmemset in libtiff/tifunix.c:340 when called from processCropSelections, tools/tiffcrop.c:7619, allowing attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit 236b7191.
