LibTIFF 4.0.6 and earlier allow remote attackers to cause a denial of
service (out-of-bounds read) via vectors related to the bytecounts[]
array variable.

- CVE-2016-3632 (arbitrary code execution)

An out-of-bounds write vulnerability was found in _TIFFVGetField
function in tif_dirinfo.c, allowing attacker to cause a denial of
service or code execution via a crafted TIFF image.

- CVE-2016-3633 (denial of service)

An out-of-bounds read vulnerability was found in the _setrow function
in the libtiff library. Using a thumbnail command on a maliciously
crafted image could cause the application to crash.

- CVE-2016-3634 (denial of service)

A vulnerability was found in the libtiff library. Using the tagCompare
function with the thumbnail command on a maliciously crafted tiff file
could cause an out-of-bounds read leading to application crash.

- CVE-2016-3658 (denial of service)

An out-of-bounds read vulnerability was found in the
TIFFWriteDirectoryTagLongLong8Array function in the libtiff library.
Using a tiffset command on a maliciously crafted image could result in
a denial-of-service.

- CVE-2016-3945 (arbitrary code execution)

When libtiff's tiff2rgba handles a maliciously-crafted tiff file(width=
8388640, height=31) an illegal write happens. 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 command via
an out-of-bounds write in the PixarLogDecode() function.

- CVE-2016-5315 (denial of service)

An out-of-bounds read vulnerability was found in in the setByteArray()
function inlibtiff. A maliciously crafted TIFF file could cause the
application to crash when using rgb2ycbcr.

- CVE-2016-5316 (denial of service)

An out-of-bounds read vulnerability was found in the PixarLogCleanup()
function 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.
