This vulnerability exists in the function cvt_by_strip (and cvt_by_tile ) due to an improper buffer allocation. An attacker may control the write address and/or value to result in denial-of-service or arbitrary code execution. - CVE-2016-3990 (arbitrary code execution) An out-of-bounds write flaw was found in libtiff v4.0.6 when using tiffcp command to handle malicious tiff file. The vulnerability exists in the function horizontalDifference8(). An attacker could control the head data of next heap which contains pre_size field and size filed to result in denial of service or arbitrary code execution. - CVE-2016-3991 (arbitrary code execution) An out-of-bounds write caused by a heap overflow when using tiffcrop tool. The vulnerability is located in the loadImage() function of tiffcrop.c. loadImage() will read the numbers of tiles by calling TIFFNumberOfTiles(). However, if the numbers of tiles is 0, loadImage() will still read tile data by calling readContigTilesIntoBuffer() from the image, regardless of the numbers. In that case, loadImage() will allocate 3 bytes of heap to store a tile data, and a heap overflow occurs if a tile data is beyond 3 bytes. This will cause denial of service or arbitrary code execution upon freeing the buffer. - CVE-2016-5102 (denial of service) A vulnerability was found in libtiff. A maliciously crafted file could cause the application to crash via buffer overflow in gif2tiff tool. - CVE-2016-5314 (arbitrary code execution) A vulnerability was found in libtiff.

A maliciously crafted TIFF file could cause the application to crash when using rgb2ycbcr. - CVE-2016-5317 (arbitrary code execution) An out-of-bounds write vulnerability was found in the PixarLogDecode() function in libtiff. A maliciously crafted TIFF file could cause the application to crash or possibly execute arbitrary code when generating a thumbnail for it. - CVE-2016-5318 (arbitrary code execution) A stack-based buffer overflow vulnerability was reported in thumbnail's _TIFFVGetField() function. Memory corruption can be triggered when handling maliciously crafted tiff file causing application to crash or possibly execute arbitrary code. - CVE-2016-5319 (arbitrary code execution) Heap-based buffer overflow vulnerability was found in tif_packbits.c in PackBitsEncode function. Memory corruption can be triggered when bmp2tiff is handling maliciously crafted bmp file causing application to crash or possibly execute arbitrary code. - CVE-2016-5320 (arbitrary code execution) An out-of-bounds write vulnerability was found in the PixarLogDecode() function in libtiff. A maliciously crafted TIFF file could cause the application to crash or even execute arbitrary code on a vulnerable machine when using the rgb2ycbcr command. - CVE-2016-5321 (denial of service) An out-of-bounds read vulnerability was found in the DumpModeDecode() function in libtiff. A maliciously crafted TIFF file could cause the application to crash when using tiffcrop command. - CVE-2016-5322 (denial of service) An out-of-bounds read vulnerability was found in the extractContigSamplesBytes() function in libtiff. A maliciously crafted TIFF file could cause the application to crash when using the tiffcrop command. - CVE-2016-5323 (denial of service) When using the tiffcrop command and a crafted TIFF image, the function _TIFFFax3fill() runs without checking the value of the divisor and causes a divide by zero flaw. Attackers can exploit this issue to cause a denial of service. - CVE-2016-5652 (arbitrary code execution) 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 via JPEG Compression Tables resulting in remote code execution. This vulnerability can be triggered via a saved TIFF file delivered by other means. - CVE-2016-5875 (arbitrary code execution) There is a heap-based buffer overflow on libtiff/tif_pixarlog.c. The vulnerability allows an attacker to control the size of the allocated heap-buffer while independently controlling the data to be written to the buffer with no restrictions on the size of the written data. - CVE-2016-6223 (information disclosure) An out-of-bounds read vulnerability on memory-mapped files in TIFFReadRawStrip1() and TIFFReadRawTile1() when stripoffset is beyond tmsize_t max value was found. The vulnerability allows an attacker to specify a negative index into the file-content buffer and copy data from that position until the end of the buffer. This will allow an attacker to crash the process by accessing unmapped memory and (depending on how LibTIFF is used) might also allow an attacker to leak sensitive information. - CVE-2016-9273 (denial of service) A heap buffer overflow has been discovered resulting in a read outside of the array boundaries leading to an application crash. - CVE-2016-9297 (denial of service) A buffer read overflow has been discovered in libtiff. The function TIFFFetchNormalTag() in libtiff/tif_dirread.c did not make sure that values of tags with TIFF_SETGET_C16_ASCII / TIFF_SETGET_C32_ASCII access are null terminated leading to potential read outside the buffer in _TIFFPrintField(). - CVE-2016-9448 (denial of service) A null pointer dereference vulnerability in TIFFFetchNormalTag() occurs when values of tags with TIFF_SETGET_C16_ASCII / TIFF_SETGET_C32_ASCII access are 0-byte arrays leading to denial of service. - CVE-2016-9453 (arbitrary code execution) An out-of-bounds write vulnerability has been discovered caused by a memcpy call without proper bounds checks. A malicious tiff file handled by tiff2pdf will cause an illegal write to a potentially attacker controlled target address. - CVE-2016-9532 (arbitrary code execution) Multiple uint32 overflows have been discovered that are leading to a heap buffer overflow in writeBufferToSeparateStrips(). A maliciously crafted TIFF file could cause the application to crash or even execute arbitrary code on a vulnerable machine. - CVE-2016-9533 (arbitrary code execution) tif_pixarlog.c in libtiff 4.0.6 has out-of-bounds write vulnerabilities in heap allocated buffers. Reported as MSVR 35094, aka "PixarLog horizontalDifference heap-buffer-overflow." - CVE-2016-9534 (arbitrary code execution) tif_write.c in libtiff 4.0.6 has an issue in the error code path of TIFFFlushData1() that didn't reset the tif_rawcc and tif_rawcp members.
