CVE-2012-2113, CVE-2012-3401).  This can be fixed by updating to 3.9.6 
and applying the four patches found here:

http://pkgs.fedoraproject.org/gitweb/?p=libtiff.git;a=tree;h=refs/heads/f17;hb=f17

There are also security vulnerabilities in the libpng packages 
(CVE-2011-3026, CVE-2011-3048, and now CVE-2012-3386).  These need to be 
updated to the latest 1.4.12, 1.2.50, and 1.0.60 releases.

PLEASE update these packages ASAP.
