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.
Buffer Overflow vulnerability found in Libtiff V.4.0.7 allows a local attacker to cause a denial of service via the tiffcp function in tiffcp.c.
A flaw was found in tiffcrop, a program distributed by the libtiff package. A specially crafted tiff file can lead to an out-of-bounds read in the extractImageSection function in tools/tiffcrop.c, resulting in a denial of service and limited information disclosure. This issue affects libtiff versions 4.x.
LibTIFF 4.4.0 has an out-of-bounds read in tiffcp in tools/tiffcp.c:948, 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 e8131125.
LibTIFF 4.4.0 has an out-of-bounds write in tiffcrop in tools/tiffcrop.c:3609, 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 33aee127.
LibTIFF 4.4.0 has an out-of-bounds write in tiffcrop in tools/tiffcrop.c:3516, 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 33aee127.
LibTIFF 4.4.0 has an out-of-bounds write in tiffcrop in tools/tiffcrop.c:3724, 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 33aee127.
LibTIFF 4.4.0 has an out-of-bounds write in tiffcrop in libtiff/tif_unix.c:368, invoked by tools/tiffcrop.c:2903 and tools/tiffcrop.c:6778, 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 33aee127.
LibTIFF 4.4.0 has an out-of-bounds write in tiffcrop in tools/tiffcrop.c:3502, 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 33aee127.

LibTIFF 4.4.0 has an out-of-bounds read in tiffcrop in tools/tiffcrop.c:3488, 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 afaabc3e.
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.
