Impressive list (most from oss-sec on Jan. 1st, right?).
I skimmed over the patches; some are obvious, others much less, but I
didn’t notice anything suspicious. I’d say go for it.
Thanks *a lot* for taking the time to prepare this patch!

Right, starting here:

I took some guidance from the Debian package versions 4.0.7-2 and
4.0.7-4:
http://metadata.ftp-master.debian.org/changelogs/main/t/tiff/tiff_4.0.7-4_changelog
I can't find a web link to the Debian packaging tree, but you can get
their patch series in the latest Debian tarball:
http://http.debian.net/debian/pool/main/t/tiff/tiff_4.0.7-4.debian.tar.xz
I generated the patches from CVS myself. The patch commentary should
help anyone who wants to reproduce the patches.
I found it difficult to name all the patches that haven't been assigned
CVE IDs yet, as you might have noticed ;)
