Hi Guys,
I am using the Perl-Modul "Image::Magick" with ImageMagick as backend. But I have a problem with converting a picture. I know, that this file is corrupted, but ImageMagick should not get a buffer-overflow. If the script trys to "Read()" the picture, it gets a "Segment Fault".
The corrupted file is a TIFF-file that should be converted to PNG.
Code: Select all
#!/usr/bin/perl -w
use strict;
use warnings;
use Image::Magick;
$|=1;
my $pic_name = "05.tif";
my $image = Image::Magick->new;
print "[start] reading\n";
my $x = $image->Read($pic_name); # hier I get the "Segment Fault"
print "[stop] reading\n"; # this text will not be displayed
my ($width,$height) = $image->Get('width','height');
$x = $image->Resize(geometry=>'400x400');
$x = $image->Write("05_big.png");
$x = $image->Resize(geometry=>'100x100');
$x = $image->Write("05_small.png");
Code: Select all
This is the test-picture:

Version: ImageMagick 6.4.4 2008-10-22 Q16 http://www.imagemagick.org
perl -MImage::Magick -e 'print "$Image::Magick::VERSION"' -> 6.4.4

We agree, ImageMagick should not fault on a corrupt image. We downloaded and converted your image with the latest ImageMagick release, 6.4.5-8, and it converted / displayed without complaint.

thanks for fast reply. Is there a posibility for you, to convert the image with the 6.4.4 version, so I can be sure, that this is a problem of this version?

Hi,
I installed the latest stable version of ImageMagick 6.4.5, but the problem still exists. I think it's a problem with the tiff-library, so I will try to install the latest BETA version of libtiff, to solve this problem. Here is the debug-log of "convert":
