An issue was discovered in function TIFFReadDirectory libtiff before 4.4.0 allows attackers to cause a denial of service via 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.

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

A NULL pointer dereference flaw was found in Libtiff's LZWDecode() function in the libtiff/tif_lzw.c file. This flaw allows a local attacker to craft specific input data that can cause the program to dereference a NULL pointer when decompressing a TIFF format file, resulting in a program crash or denial of service.

processCropSelections in tools/tiffcrop.c in LibTIFF through 4.5.0 has a heap-based buffer overflow (e.g., "WRITE of size 307203") via a crafted TIFF image.

A vulnerability was found in LibTIFF. It has been classified as critical. This affects the function TIFFReadRGBATileExt of the file libtiff/tif_getimage.c. The manipulation leads to integer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The name of the patch is 227500897dfb07fb7d27f7aa570050e62617e3be. It is recommended to apply a patch to fix this issue. The identifier VDB-213549 was assigned to this vulnerability.
