Description Brian Carp 2004-12-06 21:54:35 UTC
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:

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.

Comment 1 Brian Carp 2004-12-14 15:25:13 UTC
Segmentation fault still occurs after update following latest security advisory 
regarding ImageMagick on 8 Dec, 2004 (and the imlib libraries two days later).



Comment 2 Andreas Rogge 2005-02-01 12:10:46 UTC
I can confirm the problem still exists with ImageMagick-6.1.3-7
We're using RHEL 3 AS here.
