3. Description:

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, CVE-2016-9537, CVE-2016-9536)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

All running applications linked against libtiff must be restarted for this
update to take effect.
