"An update for libtiff is now available for Red Hat Enterprise Linux 6
and Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The libtiff packages contain a library of functions for manipulating
Tagged Image File Format (TIFF) files.

Security Fix(es) :

* Multiple flaws have been discovered in libtiff. A remote attacker
could exploit these flaws to cause a crash or memory corruption and,
possibly, execute arbitrary code by tricking an application linked
against libtiff into processing specially crafted files.
(CVE-2016-9533, CVE-2016-9534, CVE-2016-9535)

* Multiple flaws have been discovered in various libtiff tools
(tiff2pdf, tiffcrop, tiffcp, bmp2tiff). By tricking a user into
processing a specially crafted file, a remote attacker could exploit
these flaws to cause a crash or memory corruption and, possibly,
execute arbitrary code with the privileges of the user running the
libtiff tool. (CVE-2015-8870, CVE-2016-5652, CVE-2016-9540,

Red Hat Product Security has rated this update as having a security

vulnerability from the CVE link(s) in the References section.

The libtiff packages contain a library of functions for manipulating
Tagged Image File Format (TIFF) files.

Security Fix(es) :

* Multiple flaws have been discovered in libtiff. A remote attacker
could exploit these flaws to cause a crash or memory corruption and,
possibly, execute arbitrary code by tricking an application linked
against libtiff into processing specially crafted files.
