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.

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

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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.
