CVE-2023-25433 is a heap-based buffer overflow in the tiffcrop utility distributed with libtiff 4.5.0. Incorrect buffer-size updating after rotateImage() can cause an out-of-bounds heap write while processing crop selections. A specially crafted TIFF file processed by tiffcrop can trigger the flaw and cause a segmentation fault.
