The LZWEncode function in tif_lzw.c in the bmp2tiff tool in LibTIFF 4.0.6 and earlier, when the "-c lzw" option is used, allows remote attackers to cause a denial of service (buffer over-read) via a crafted BMP image.

The remote Redhat Enterprise Linux 5 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 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.
    (CVE-2014-8128)

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

This plugin has been deprecated as it does not adhere to established standards for this style of check.

This update for tiff fixes the following issues :

Security issues fixed :

CVE-2018-18661: Fixed NULL pointer dereference in the function LZWDecode in the file tif_lzw.c (bsc#1113672).

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.
