The following issues have been reported as fixed in Version 4.0.6-2, I guess a backport is possible:

* PixarLogDecode() out-of-bound writes (CVE-2016-5314)
* tif_pixarlog.c: PixarLogCleanup() Segmentation fault (CVE-2016-5316)
* rgb2ycbcr: command excution (CVE-2016-5320)
* DumpModeDecode(): Ddos (CVE-2016-5321)
* tiffcrop _TIFFFax3fillruns(): NULL pointer dereference (CVE-2016-5323)
* tiff: heap-based buffer overflow when using the PixarLog compression format (CVE-2016-5875)
* tiff: information leak in libtiff/tif_read.c (CVE-2016-6223)

Of these CVE-2016-5320 has the highest impact
 CVSS v2 Base score 6.8 AV:N/AC:M/Au:N/C:P/I:P/A:P
