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-2014-9655, CVE-2015-1547,
CVE-2015-8784, CVE-2015-8683, CVE-2015-8665, CVE-2015-8781, CVE-2015-8782,
CVE-2015-8783, CVE-2016-3990, CVE-2016-5320)

* Multiple flaws have been discovered in various libtiff tools (bmp2tiff,
pal2rgb, thumbnail, tiff2bw, tiff2pdf, tiffcrop, tiffdither, tiffsplit,
tiff2rgba). 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-2014-8127, CVE-2014-8129,
CVE-2014-8130, CVE-2014-9330, CVE-2015-7554, CVE-2015-8668, CVE-2016-3632,
CVE-2016-3945, CVE-2016-3991)

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.
