Subject: [FD] Three out of bounds access issues in ImageMagick
 (CVE-2014-8354, CVE-2014-8355, CVE-2014-8562)

Found this with the help of fuzzing / address sanitizer.
Nothing to worry about too much, unlikely to cause any severe issues,
but it's interesting how many issues there are that can be trivially
found via fuzzing.
Please note also that imagemagick 6.8.9-9 fixes another issue that got
CVE-2014-8561:

CVE-2014-8354: ImageMagick - Out-of-bounds read / heap overflow in
resize code

Description
===========

ImageMagick is vulnerable to an out of bounds read / heap overflow in
the function HorizontalFilter() in the file resize.c. It is triggered
if an image has dimensions 0x0. The issue has been found with the help
of Address Sanitizer and the fuzzing tool zzuf.

Solution
========

ImageMagick has released version 6.8.9-9 which fixes this and some
other out-of-bounds issues. GraphicsMagick, which is a fork of
ImageMagick, is not affected.
