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.

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.

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

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.

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.

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.
