Control: notfound 878544 8:6.8.9.9-5+deb8u10
Control: notfound 878544 8:6.7.7.10-5+deb7u18
Control: found 878544 8:6.9.7.4+dfsg-11+deb9

I have tried to reproduce this issue in wheezy LTS and jessie. I could
not produce a crash. Valgrind is similarly happy so I presume the issue
was introduced somewhere after jessie.

Hopefully the above control-fu will reflect that in the BTS.

Here's the output on jessie:

vagrant at jessie:~$ convert tiff_uaf_TIFFSetField /dev/null
TIFFWriteDirectoryTagData: IO error writing tag data.
convert: Incorrect value for "ICC Profile"; tag ignored. `TIFFFetchNormalTag' @ warning/tiff.c/TIFFWarnings/881.
convert: IO error writing tag data. `TIFFWriteDirectoryTagData' @ error/tiff.c/TIFFErrors/569.

and wheezy:

vagrant at wheezy:~$ convert tiff_uaf_TIFFSetField /dev/null
convert.im6: tiff_uaf_TIFFSetField: wrong data type 4 for "ICC Profile"; tag ignored. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/788.
convert.im6: Error writing data for field "BitsPerSample". `/dev/null' @ error/tiff.c/TIFFErrors/515.

and stretch, which *does* suffer from the problem:
