There exists one heap buffer overflow in _TIFFmemcpy in tif_unix.c in libtiff 4.0.10, which allows an attacker to cause a denial-of-service through a crafted tiff file.

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.

A null pointer dereference issue was found in Libtiff's tif_dir.c file. This issue may allow an attacker to pass a crafted TIFF image file to the tiffcp utility which triggers a runtime error that causes undefined behavior. This will result in an application crash, eventually leading to a denial of service.

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.

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.

libtiff 4.5.0 is vulnerable to Buffer Overflow via extractContigSamplesShifted8bits() at /libtiff/tools/tiffcrop.c:3753.

A NULL pointer dereference in TIFFClose() is caused by a failure to open an output file (non-existent path or a path that requires permissions like /dev/null) while specifying zones.

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

libtiff 4.5.0 is vulnerable to Buffer Overflow via extractContigSamplesBytes() at /libtiff/tools/tiffcrop.c:3215.

A vulnerability was found in the libtiff library. This security flaw causes a heap buffer overflow in extractContigSamples32bits, tiffcrop.c.
