The setByteArray function in tif_dir.c in libtiff 4.0.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted tiff 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 :

(bsc#1033112)

  - CVE-2017-7601: LibTIFF had a 'shift exponent too large     for 64-bit type long' undefined behavior issue, which     might have allowed remote attackers to cause a denial of     service (application crash) or possibly have unspecified     other impact via a crafted image. (bsc#1033111)

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.

    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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Multiple vulnerabilities have been discovered in the libtiff library and the included tools tiff2rgba, rgb2ycbcr, tiffcp, tiffcrop, tiff2pdf and tiffsplit, which may result in denial of service, memory disclosure or the execution of arbitrary code.

There were additional vulnerabilities in the tools bmp2tiff, gif2tiff, thumbnail and ras2tiff, but since these were addressed by the libtiff developers by removing the tools altogether, no patches are available and those tools were also removed from the tiff package in Debian stable. The change had already been made in Debian stretch before and no applications included in Debian are known to rely on these scripts.
If you use those tools in custom setups, consider using a different conversion/thumbnailing tool.

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 3.9.6-11+deb7u1 and 3.9.6-11+deb7u2 introduced changes that resulted in libtiff writing out invalid tiff files when the compression scheme in use relies on codec-specific TIFF tags embedded in the image.

For Debian 7 'Wheezy', these problems have been fixed in version 3.9.6-11+deb7u3.

We recommend that you upgrade your tiff3 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.

Several vulnerabilities were found in the tiff library, potentially causing denial of services to applications using it.

For Debian 7 'Wheezy', these problems have been fixed in version 4.0.2-6+deb7u6.

We recommend that you upgrade your tiff packages.
