It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system were tricked into opening a specially crafted image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.

According to the versions of the compat-libtiff3 package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The (1) putcontig8bitYCbCr21tile function in     tif_getimage.c or (2) NeXTDecode function in tif_next.c     in LibTIFF allows remote attackers to cause a denial of     service (uninitialized memory access) via a crafted     TIFF image, as demonstrated by libtiff-cvs-1.tif and     libtiff-cvs-2.tif.(CVE-2014-8127,CVE-2014-8129,CVE-2014
    -8130,CVE-2014-9655)

  - A flaw was discovered in the bmp2tiff utility. By     tricking a user into processing a specially crafted     file, a remote attacker could exploit this flaw to     cause a crash or memory corruption and, possibly,     execute arbitrary code with the privileges of the user     running the libtiff     tool.(CVE-2014-9330,CVE-2015-7554,CVE-2015-8668,CVE-201     5-8665,CVE-2015-8781,CVE-2016-3632,CVE-2016-3945,CVE-20     16-3990,CVE-2016-3991,CVE-2016-5320,CVE-2016-5652,CVE-2     015-8683)

    Reported as MSVR 35103, aka 'cpStripToTile     heap-buffer-overflow.'(CVE-2016-9540)

  - tif_predict.h and tif_predict.c in libtiff have     assertions that can lead to assertion failures in debug     mode, or buffer overflows in release mode, when dealing     with unusual tile size like YCbCr with subsampling.
    Reported as MSVR 35105, aka 'Predictor     heap-buffer-overflow.'(CVE-2016-9535,CVE-2016-9533,CVE-     2016-9534,CVE-2016-9536,CVE-2016-9537)

  - The NeXTDecode function in tif_next.c in LibTIFF allows     remote attackers to cause a denial of service     (uninitialized memory access) via a crafted TIFF image,     as demonstrated by libtiff5.tif.(CVE-2015-1547)

libtiff project reports :

Multiple flaws have been discovered in libtiff library and utilities.

Multiple flaws have been discovered in libtiff. A remote attacker could exploit these flaws to cause a crash or memory corruption and, possibly, execute arbitrary code by tricking an application linked against libtiff into processing specially crafted files.
(CVE-2016-9533 , CVE-2016-9534 , CVE-2016-9535)

Multiple flaws have been discovered in various libtiff tools (tiff2pdf, tiffcrop, tiffcp, bmp2tiff). By tricking a user into processing a specially crafted file, a remote attacker could exploit these flaws to cause a crash or memory corruption and, possibly, execute arbitrary code with the privileges of the user running the libtiff tool. (CVE-2015-8870 , CVE-2016-5652 , CVE-2016-9540 , CVE-2016-9537 , CVE-2016-9536)

Numerous security vulnerabilities have been found through fuzzing on various tiff-related binaries. Crafted TIFF images allows remote attacks to cause denial of service or, in certain cases arbitrary code execution through divide-by-zero, out of bunds write, integer and heap overflow.

CVE-2016-3622

The fpAcc function in tif_predict.c in the tiff2rgba tool in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (divide-by-zero error) via a crafted TIFF image.

CVE-2016-3623

The rgb2ycbcr tool in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (divide-by-zero) by setting the (1) v or (2) h parameter to 0. (Fixed along with CVE-2016-3624.)

CVE-2016-3624

The cvtClump function in the rgb2ycbcr tool in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds write) by setting the '-v' option to -1.

CVE-2016-3945

Multiple integer overflows in the (1) cvt_by_strip and (2) cvt_by_tile functions in the tiff2rgba tool in LibTIFF 4.0.6 and earlier, when -b mode is enabled, allow remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted TIFF image, which triggers an out-of-bounds write.

CVE-2016-3990

Heap-based buffer overflow in the horizontalDifference8 function in tif_pixarlog.c in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted TIFF image to tiffcp.

CVE-2016-9533

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

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. Reported as MSVR 35095, aka 'TIFFFlushData1 heap-buffer-overflow.'

CVE-2016-9535

tif_predict.h and tif_predict.c in libtiff 4.0.6 have assertions that can lead to assertion failures in debug mode, or buffer overflows in release mode, when dealing with unusual tile size like YCbCr with subsampling. Reported as MSVR 35105, aka 'Predictor heap-buffer-overflow.'

CVE-2016-9536

tools/tiff2pdf.c in libtiff 4.0.6 has out-of-bounds write vulnerabilities in heap allocated buffers in t2p_process_jpeg_strip().
Reported as MSVR 35098, aka 't2p_process_jpeg_strip heap-buffer-overflow.'

CVE-2016-9537

tools/tiffcrop.c in libtiff 4.0.6 has out-of-bounds write vulnerabilities in buffers. Reported as MSVR 35093, MSVR 35096, and MSVR 35097.

CVE-2016-9538

tools/tiffcrop.c in libtiff 4.0.6 reads an undefined buffer in readContigStripsIntoBuffer() because of a uint16 integer overflow.
Reported as MSVR 35100.

CVE-2016-9540

tools/tiffcp.c in libtiff 4.0.6 has an out-of-bounds write on tiled images with odd tile width versus image width. Reported as MSVR 35103, aka cpStripToTile heap-buffer-overflow.

CVE-2016-10092

heap-buffer-overflow in tiffcrop

CVE-2016-10093 uint32 underflow/overflow that can cause heap-based buffer overflow in tiffcp

CVE-2017-5225

LibTIFF version 4.0.7 is vulnerable to a heap buffer overflow in the tools/tiffcp resulting in DoS or code execution via a crafted BitsPerSample value.

Bug #846837

heap-based buffer verflow in TIFFFillStrip (tif_read.c)

For Debian 7 'Wheezy', these problems have been fixed in version 4.0.2-6+deb7u9.

We recommend that you upgrade your tiff packages.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libtiff: Heap-based buffer over-read in bmp2tiff (CVE-2017-9117)

  - 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.
    (CVE-2014-8128)

  - Integer overflow in tools/bmp2tiff.c in LibTIFF before 4.0.4 allows remote attackers to cause a denial of     service (heap-based buffer over-read), or possibly obtain sensitive information from process memory, via     crafted width and length values in RLE4 or RLE8 data in a BMP file. (CVE-2015-8870)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

tiff3 受到多个问题的影响，这些问题至少可导致使用 libtiff4 的应用程序拒绝服务。可提供特制的 TIFF 文件来触发：通过失败断言进行 abort() 调用、缓冲区溢出（读取和写入模式均出现）。CVE-2015-8781 libtiff 中的 tif_luv.c 允许攻击者通过 LogL 压缩的 TIFF 图像中每像素无效数量的样本导致拒绝服务（越界写入）。CVE-2015-8782 libtiff 中的 tif_luv.c 允许攻击者通过特制的 TIFF 图像导致拒绝服务（越界写入）。CVE-2015-8783 libtiff 中的 tif_luv.c 允许攻击者通过特制的 TIFF 图像导致拒绝服务（越界读取）。CVE-2015-8784 libtiff 中 tif_next.c 中的 NeXTDecode 函数允许远程攻击者通过特制的 TIFF 图像导致拒绝服务（越界写入）。CVE-2016-9533 libtiff 4.0.6 中的 tif_pixarlog.c 在堆分配的缓冲区中有越界写入漏洞。CVE-2016-9534 libtiff 4.0.6 中的 tif_write.c 在 TIFFFlushData1() 的错误代码路径中存在一个问题，未重置 tif_rawcc 和 tif_rawcp 成员。CVE-2016-9535 libtiff 4.0.6 中的 tif_predict.h 和 tif_predict.c 存在断言，在使用子采样处理 YCbCr 等不寻常的切片大小时，可能会导致调试模式下的断言失败，或者发布模式下的缓冲区溢出。对于 Debian 7“Wheezy”，这些问题已在 3.9.6-11+deb7u4 版本中修复。我们建议您升级 tiff3 程序包。注意：Tenable Network Security 已直接从 DLA 安全公告中提取上述描述块。Tenable 已尝试在不引入其他问题的情况下，尽可能进行自动整理和排版。
