Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
libtiff 4.5.0 is vulnerable to Buffer Overflow in uv_encode() when libtiff reads a corrupted little-endian TIFF file and specifies the output to be big-endian.

NULL Pointer Dereference
A null pointer dereference issue was discovered in Libtiff's tif_dir.c file. This flaw allows an attacker to pass a crafted TIFF image file to the tiffcp utility, which triggers runtime error, causing an undefined behavior, resulting in an application crash, eventually leading to a denial of service.

Out-of-bounds Write
loadImage() in tools/tiffcrop.c in LibTIFF through 4.5.0 has a heap-based use after free via a crafted TIFF image.

Missing Release of Memory after Effective Lifetime
A memory leak flaw was found in Libtiff's tiffcrop utility. This issue occurs when tiffcrop operates on a TIFF image file, allowing an attacker to pass a crafted TIFF image file to tiffcrop utility, which causes this memory leak issue, resulting an application crash, eventually leading to a denial of service.

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
A flaw was found in libtiff. A specially crafted tiff file can lead to a segmentation fault due to a buffer overflow in the Fax3Encode function in libtiff/tif_fax3.c, resulting in a denial of service.

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
libtiff 4.5.0 is vulnerable to Buffer Overflow via /libtiff/tools/tiffcrop.c:8499. Incorrect updating of buffer size after rotateImage() in tiffcrop cause heap-buffer-overflow and SEGV.
