ImageMagick tools appear to be generating segmentation faults with the conversion of images to TIFF. I have only noticed this problem since the latest upgrade to the ImageMagick suite as of Oct 20, 2004 and the libtiff package on the Oct 22 (see URL, above). For example, running 'covert' on a valid JPEG or PNG file to the standard output in TIFF format (using 'tif:-') will result in a segmentation fault. Using a simple filename ('test.tif') will succeed, but running 'identify' on the newly created file results in a segmentation fault. For some reason, converting first to PNG and then to TIFF (through actual files) appears to work successfully, even though direct conversion from a JPEG or conversion through a pipe will fail. Version-Release number of selected component (if applicable): ImageMagick-5.5.6-6, libtiff-3.5.7-20.1 How reproducible: Always Steps to Reproduce: 1. Locate a valid image file, e.g. test.jpg or test.png 2. convert test.png tif:- > /dev/null 3. convert test.jpg test.tif Actual Results: Segmentation fault (core dumped) Expected Results: Valid image file created after converstion, no segmentation fault, and no errors printed to the standard error.
Segmentation fault still occurs after update following latest security advisory regarding ImageMagick on 8 Dec, 2004 (and the imlib libraries two days later).

I can confirm the problem still exists with ImageMagick-6.1.3-7 We're using RHEL 3 AS here.
