Assuming that the necessary fixes were to libtiff rather than libjpeg, 
the best thing to do is to submit a patch to the libtiff bug tracking 
system at 
"http://bugzilla.remotesensing.org/enter_bug.cgi?product=libtiff". 
You will want to set up an account on this system using your email 
address as the login ID.

CVS can be used to generate a patch by doing

   cvs diff -u -N > libtiff.patch

I find that putting a .cvsrc file in my home directory which contains 
the following:

cvs -z3
update -P -d
checkout -P
diff -u -N

helps provide nice default options.
