Vulnerabilities (CVE)

In LibTIFF 4.0.6 and possibly other versions, the program processes BMP images without verifying that biWidth and biHeight in the bitmap-information header match the actual input, as demonstrated by a heap-based buffer over-read in bmp2tiff. NOTE: mentioning bmp2tiff does not imply that the activation point is in the bmp2tiff.c file (which was removed before the 4.0.7 release).

The t2p_readwrite_pdf_image_tile function in LibTIFF allows remote attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a JPEG file with a TIFFTAG_JPEGTABLES of length one.

In LibTIFF 4.0.8, there is a heap-based use-after-free in the t2p_writeproc function in tiff2pdf.c. NOTE: there is a third-party report of inability to reproduce this issue

The putagreytile function in tif_getimage.c in LibTIFF 4.0.7 has a left-shift undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image.

In LibTIFF 4.0.7, the TIFFReadDirEntryLong8Array function in libtiff/tif_dirread.c mishandles a malloc operation, which allows attackers to cause a denial of service (memory leak within the function _TIFFmalloc in tif_unix.c) via a crafted file.

LibTIFF 4.0.7 has an "outside the range of representable values of type float" undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image.

Stack-based buffer overflow in the _TIFFVGetField function in tif_dir.c in LibTIFF 4.0.0alpha4, 4.0.0alpha5, 4.0.0alpha6, 4.0.0beta7, 4.0.0, 4.0.1, 4.0.2, 4.0.3, 4.0.4, 4.0.4beta, 4.0.5, 4.0.6, 4.0.7 and 4.0.8 allows remote attackers to cause a denial of service (crash) via a crafted TIFF file.

Heap-based buffer overflow in tif_packbits.c in libtiff 4.0.6 and earlier allows remote attackers to crash the application via a crafted bmp file.

The TIFFReadRawStrip1 and TIFFReadRawTile1 functions in tif_read.c in libtiff before 4.0.7 allows remote attackers to cause a denial of service (crash) or possibly obtain sensitive information via a negative index in a file-content buffer.

tools/tiffcrop.c in LibTIFF 4.0.7 allows remote attackers to cause a denial of service (heap-based buffer over-read and buffer overflow) or possibly have unspecified other impact via a crafted TIFF image, related to "READ of size 1" and libtiff/tif_fax3.c:413:13.

In LibTIFF 4.0.8, there is a heap-based buffer overflow in the t2p_write_pdf function in tools/tiff2pdf.c. This heap overflow could lead to different damages. For example, a crafted TIFF document can lead to an out-of-bounds read in TIFFCleanup, an invalid free in TIFFClose or t2p_free, memory corruption in t2p_readwrite_pdf_image, or a double free in t2p_free. Given these possibilities, it probably could cause arbitrary code execution.

There is a reachable assertion abort in the function TIFFWriteDirectorySec() in LibTIFF 4.0.8, related to tif_dirwrite.c and a SubIFD tag. A crafted input will lead to a remote denial of service attack.

The TIFFReadDirEntryArray function in tif_read.c in LibTIFF 4.0.8 mishandles memory allocation for short files, which allows remote attackers to cause a denial of service (allocation failure and application crash) in the TIFFFetchStripThing function in tif_dirread.c during a tiff2pdf invocation.

The TIFFFetchNormalTag function in LibTiff 4.0.6 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) by setting the tags TIFF_SETGET_C16ASCII or TIFF_SETGET_C32_ASCII to values that access 0-byte arrays. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9297.

An exploitable heap-based buffer overflow exists in the handling of TIFF images in LibTIFF's TIFF2PDF tool. A crafted TIFF document can lead to a heap-based buffer overflow resulting in remote code execution. Vulnerability can be triggered via a saved TIFF file delivered by other means.

In LibTIFF 4.0.8, there is a denial of service vulnerability in the TIFFOpen function. A crafted input will lead to a denial of service attack. During the TIFFOpen process, td_imagelength is not checked. The value of td_imagelength can be directly controlled by an input file. In the ChopUpSingleUncompressedStrip function, the _TIFFCheckMalloc function is called based on td_imagelength. If we set the value of td_imagelength close to the amount of system memory, it will hang the system or trigger ...
