Summary
=======

The package libtiff and lib32-libtiff are vulnerable to arbitrary code execution via CVE-2016-10095 and CVE-2015-7554.

Guidance
========

CVE-2015-7554: An Invalid memory write flaw was found in libtiff in the way it parsed certain extension tags when reading TIFF format files. A remote attacker could use this flaw to crash or even execute arbitrary code with the permission of the user running such an application compiled against libtiff.
CVE-2016-10095: A stack-based buffer overflow vulnerability was found in libtiff when running tiffslpit on crafted tiff file.

For CVE-2015-7554 Debian bugtracker claim to be fixed in 4.0.8-2 therefor maybe it need a patch for both packages.
For CVE-2016-10095 aparently the same 4.0.8-2 fix the problem.

Yet there is CVE-2017-9935 not fixed on 4.0.8-2 but should be on upstream 4.0.9 or by debian the fist one to serve.
