Adobe Elements Jpeg files and bad comments, crash.

[wilburlo]

I believe a found a bug in image magick 6.3.5

Apparently Adobe Photoshop Elements 4.0 (On Mac) places some extra comment
blocks in it's jpeg files.

When I attempt to "identify" the file, identify crashes with this error message

# identify adobe_bad_comment.jpg
identify in realloc(): warning: junk pointer, too high to make sense
identify in free(): warning: junk pointer, too high to make sense
identify: unable to allocate string `begin="" id="W5M0MpCehiHzreSzNTczkc9d"'.

After I run "jpegtran -copy none" on the file, "identify" has no problems with
it.

# jpegtran -copy none adobe_bad_comment.jpg > adobe_cleaned.jpg

# identify adobe_cleaned.jpg
adobe_cleaned.jpg JPEG 743x557 743x557+0+0 DirectClass 8-bit 106.908kb

Here is the bad commented image:

Here is the no commentes image

Will you be able to place a fix for this in 6.3.5-1?

This bug is not present in 6.3.3, FYI.

TIA,

6.3.5 parses the XMP profile. Apparently its tickling a bug in the XML parser although identifying your image under Fedora Linux seems to work fine. Will investigate further sometime this week.

If there is any information I can get you, please let me know.


Thank you,

Grab ImageMagick 6.3.5-1 from ftp://magick.imagemagick.org/pub/ImageMagick/beta in about an hour (its building now). See if the patch to magick./xml-tree.c fixed the problem.

We were not able to reproduce this error with Image-Magick 6.3.5-1 beta.

Thank you for the bug fix!!!
