Divide By Zero error in tiffcrop in libtiff 4.3.0 allows 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 f8d0f9aa.

Null source pointer passed as an argument to memcpy() function within TIFFFetchNormalTag () in tif_dirread.c in libtiff versions up to 4.3.0 could lead to Denial of Service via crafted TIFF file.

Unchecked Return Value to NULL Pointer Dereference in tiffcrop in libtiff 4.3.0 allows 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 f2b656e2.

A heap buffer overflow in ExtractImageSection function in tiffcrop.c in libtiff library Version 4.3.0 allows attacker to trigger unsafe or out of bounds memory access via crafted TIFF image file which could result into application crash, potential information disclosure or any other context-dependent impact

Reachable Assertion in tiffcp in libtiff 4.3.0 allows 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 5e180045.

Null source pointer passed as an argument to memcpy() function within TIFFReadDirectory() in tif_dirread.c in libtiff versions from 4.0 to 4.3.0 could lead to Denial of Service via crafted TIFF file. For users that compile libtiff from sources, a fix is available with commit 561599c.

Null source pointer passed as an argument to memcpy() function within TIFFFetchStripThing() in tif_dirread.c in libtiff versions from 3.9.0 to 4.3.0 could lead to Denial of Service via crafted TIFF file. For users that compile libtiff from sources, the fix is available with commit eecb0712.

LibTIFF 4.3.0 has an out-of-bounds read in _TIFFmemcpy in tif_unix.c in certain situations involving a custom tag and 0x0200 as the second word of the DE field.

Buffer Overflow in LibTiff v4.0.10 allows attackers to cause a denial of service via the 'in _TIFFmemcpy' funtion in the component 'tif_unix.c'.

Buffer Overflow in LibTiff v4.0.10 allows attackers to cause a denial of service via the "TIFFVGetField" funtion in the component 'libtiff/tif_dir.c'.

Buffer Overflow in LibTiff v4.0.10 allows attackers to cause a denial of service via the "invertImage()" function in the component "tiffcrop".

A heap-based buffer overflow flaw was found in libtiff in the handling of TIFF images in libtiff's TIFF2PDF tool. A specially crafted TIFF file can lead to arbitrary code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

An integer overflow flaw was found in libtiff that exists in the tif_getimage.c file. This flaw allows an attacker to inject and execute arbitrary code when a user opens a crafted TIFF file. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

In LibTIFF, there is a memory malloc failure in tif_pixarlog.c. A crafted TIFF document can lead to an abort, resulting in a remote denial of service attack.

A flaw was found in libtiff. Due to a memory allocation failure in tif_read.c, a crafted TIFF file can lead to an abort, resulting in denial of service.

LibTIFF prior to 4.0.4, as used in Apple iOS before 8.4 and OS X before 10.10.4 and other products, allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted TIFF image.

tif_getimage.c in LibTIFF through 4.0.10, as used in GDAL through 3.0.1 and other products, has an integer overflow that potentially causes a heap-based buffer overflow via a crafted RGBA image, related to a "Negative-size-param" condition.

_TIFFCheckMalloc and _TIFFCheckRealloc in tif_aux.c in LibTIFF through 4.0.10 mishandle Integer Overflow checks because they rely on compiler behavior that is undefined by the applicable C standards. This can, for example, lead to an application crash.

LibTIFF 4.0.8 has multiple memory leak vulnerabilities, which allow attackers to cause a denial of service (memory consumption), as demonstrated by tif_open.c, tif_lzw.c, and tif_aux.c. NOTE: Third parties were unable to reproduce the issue

An Invalid Address dereference was discovered in TIFFWriteDirectoryTagTransferfunction in libtiff/tif_dirwrite.c in LibTIFF 4.0.10, affecting the cpSeparateBufToContigBuf function in tiffcp.c. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted tiff file. This is different…
