An exploitable remote code execution vulnerability exists in the handling of TIFF images in LibTIFF version 4.0.6. A crafted TIFF document can lead to a type confusion vulnerability resulting in remote code execution. This vulnerability can be triggered via a TIFF file delivered to the application using LibTIFF's tag extension functionality.

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.

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

  - LibTIFF 4.0.3 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a     crafted TIFF image to the (1) checkInkNamesString function in tif_dir.c in the thumbnail tool, (2)     compresscontig function in tiff2bw.c in the tiff2bw tool, (3) putcontig8bitCIELab function in     tif_getimage.c in the tiff2rgba tool, LZWPreDecode function in tif_lzw.c in the (4) tiff2ps or (5)     tiffdither tool, (6) NeXTDecode function in tif_next.c in the tiffmedian tool, or (7)     TIFFWriteDirectoryTagLongLong8Array function in tif_dirwrite.c in the tiffset tool. (CVE-2014-8127)

  - 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.

This update for tiff fixes the following security issues :

  - CVE-2017-5225: Prevent heap buffer overflow in the     tools/tiffcp that could have caused DoS or code     execution via a crafted BitsPerSample value     (bsc#1019611)

  - CVE-2018-7456: Prevent a NULL pointer dereference in the     function TIFFPrintDirectory when using the tiffinfo tool     to print crafted TIFF information, a different     vulnerability than CVE-2017-18013 (bsc#1082825)

  - CVE-2017-11613: Prevent denial of service in the     TIFFOpen function. 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 the value of td_imagelength is set     close to the amount of system memory, it will hang the     system or trigger the OOM killer (bsc#1082332)

  - CVE-2016-10266: Prevent remote attackers to cause a     denial of service (divide-by-zero error and application     crash) via a crafted TIFF image, related to     libtiff/tif_read.c:351:22 (bsc#1031263)

  - CVE-2018-8905: Prevent heap-based buffer overflow in the     function LZWDecodeCompat via a crafted TIFF file     (bsc#1086408)

  - Removed assert in readSeparateTilesIntoBuffer() function     (bsc#1017689).

  - CVE-2016-10095: Prevent stack-based buffer overflow in     the _TIFFVGetField function that allowed remote     attackers to cause a denial of service (crash) via a     crafted TIFF file (bsc#1017690).

  - CVE-2016-8331: Prevent remote code execution because of     incorrect handling of TIFF images. A crafted TIFF     document could have lead to a type confusion     vulnerability resulting in remote code execution. This     vulnerability could have been be triggered via a TIFF     file delivered to the application using LibTIFF's tag     extension functionality (bsc#1007276).

  - CVE-2016-3632: The _TIFFVGetField function allowed     remote attackers to cause a denial of service     (out-of-bounds write) or execute arbitrary code via a     crafted TIFF image (bsc#974621).

USN-3212-1 and USN-3212-2 fixed a vulnerabilitiy in LibTIFF. This update provides a subset of corresponding update for Ubuntu 12.04 ESM.

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.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3212-1 advisory.

The remote host is affected by the vulnerability described in GLSA-201701-16 (libTIFF: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in libTIFF. Please review       the CVE identifier and bug reports referenced for details.
  Impact :

    A remote attacker could entice a user to process a specially crafted       image file, possibly resulting in execution of arbitrary code with the       privileges of the process or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

Version 4.0.2-6+deb7u7 introduced changes that resulted in libtiff being unable to write out tiff files when the compression scheme in use relies on codec-specific TIFF tags embedded in the image.

This problem manifested itself with errors like those: $ tiffcp -r 16
-c jpeg sample.tif out.tif _TIFFVGetField: out.tif: Invalid tag 'Predictor' (not supported by codec). _TIFFVGetField: out.tif: Invalid tag 'BadFaxLines' (not supported by codec). tiffcp:
tif_dirwrite.c:687: TIFFWriteDirectorySec: Assertion `0' failed.

For Debian 7 'Wheezy', these problems have been fixed in version 4.0.2-6+deb7u10.

We recommend that you upgrade your tiff packages.
