Package: libmagick++5
Version: 8:6.7.7.10-3.1
Severity: important
Tags: upstream patch fixed-upstream
On some PNG images, ImageMagick fails with an assertion in the read method.
This happens because ImageMagick does not determine the maximum number of
threads in a uniform way. In my case, this broke a django web application,
so this problem could be used to conduct a DoS attack in some environments.
I have reported the problem upstream at
http://www.imagemagick.org/discourse-server/viewtopic.php?f=23&t=21741
It turned out that the problem has been fixed after the release that's
currently in Debian wheezy.
Could this problem be fixed please for wheezy?
Patch extracted from upstream SVN attached.
