Thanks for reporting this issue and for the updated patch. I'll prepare
a security regression updates and will publish them this week, likely

Thanks!

Bug description:
The patches applied to libtiff 4.0.6 in 4.0.6-2ubuntu01 seem to break
JPEG tiff read and write.
To reproduce:
$ tiffcp -c jpeg k2a.tif x.tif
(where k2a.tif is a simple uncompressed RGB strip tiff) appears to
work. However, x.tif, the output, will now not read without warnings:
$ tiffcp x.tif y.tif
TIFFFetchNormalTag: Warning, ASCII value for tag "JPEGTables" does not end in
null byte. Forcing it to be null.
JPEGLib: Warning, Premature end of JPEG file.
This was working fine until a couple of days ago, so I guess it's one
of the most recent patches.
Some packages using libtiff seem to be broken too. For example,
openslide, which uses libtiff to load jp2k-compressed slide images, is
no longer working:
$ openslide-write-png CMU-1-Small-Region.svs 0 0 0 100 100 x.png
TIFFFetchNormalTag: Warning, ASCII value for tag "JPEGTables" does not end in
null byte. Forcing it to be null.
TIFFFetchNormalTag: Warning, ASCII value for tag "JPEGTables" does not end in
null byte. Forcing it ... repeats 8 more times
openslide-write-png: Premature end of JPEG file
and x.png is not a valid PNG image. The test .svs image may be
downloaded here:
http://openslide.cs.cmu.edu/download/openslide-testdata/Aperio/
