Comment 13 for bug 18289

OK, maybe you won't be out of luck. After reading Pete Savage's blog post about recovering data, I was able to extract the jpeg living inside my tiff and finally view the image as intended. Others may find the "foremost" program helpful: https://launchpad.net/distros/ubuntu/+source/foremost

foremost was able to discover 2 jpegs (one thumbnail as well as the original scan) and an OLE document inside the evil TIFF, and it extracted them into their own files.
Just run it like so: "foremost evil.tiff" and it'll put all the files it finds underneath and "output" directory.
