tiff - security update

Murray McAllister discovered a heap-based buffer overflow in the gif2tiff
command line tool. Executing gif2tiff on a malicious tiff image could
result in arbitrary code execution.

For the stable distribution (wheezy), this problem has been fixed in
version 4.0.2-6+deb7u3.

For the testing distribution (jessie), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 4.0.3-9.

We recommend that you upgrade your tiff packages.
