[Pkg-gmagick-im-team] Bug#835488: imagemagick: Regression after security update to 8:6.8.9.9-5+deb8u4, unable to convert PDF files in PHP

[Tommie Van Mechgelen]

Package: imagemagick
Version: 8:6.8.9.9-5+deb8u4
Severity: important

Dear Maintainer,

After the upgrade to this version, converting PDF-files in PHP stopped working.

A small PHP test application throws an exception.

---
unable to read image data `/tmp/magick-28249kJukMY5BQuJr1' @ error/pnm.c/ReadPNMImage/617
The PDF contains 0 pages
---

The expected result is no exception and it should display the number of pages.  This worked with version 8:6.8.9.9-5+deb8u3.

Thanks for investigating this.

PHP code:
---------
<?php

$imagick = new Imagick();
try {
    $imagick->pingImage('bug.pdf');
}
catch(ImagickException $e) {
    print $e->getMessage() . "\n";
}

$pages = $imagick->getNumberImages();
print "The PDF contains $pages pages\n";
