Title:RedHat Security Advisory RHSA-2012:0301
The remote host is missing updates announced in
advisory RHSA-2012:0301.

ImageMagick is an image display and manipulation tool for the X Window
System that can read and write multiple image formats.

It was found that ImageMagick utilities tried to load ImageMagick
configuration files from the current working directory. If a user ran an
ImageMagick utility in an attacker-controlled directory containing a
specially-crafted ImageMagick configuration file, it could cause the
utility to execute arbitrary code. (CVE-2010-4167)

This update also fixes the following bugs:

* Previously, the identify -verbose command failed with an assertion if
there was no image information available. An upstream patch has been
applied, so that GetImageOption() is now called correctly. Now, the
identify -verbose command works correctly even if no image information is
available. (BZ#502626)

* Previously, an incorrect use of the semaphore data type led to a
deadlock. As a consequence, the ImageMagick utility could become
unresponsive when converting JPEG files to PDF (Portable Document Format)
files. A patch has been applied to address the deadlock issue, and JPEG
files can now be properly converted to PDF files. (BZ#530592)

* Previously, running the convert command with the -color option failed
with a memory allocation error. The source code has been modified to fix
problems with memory allocation. Now, using the convert command with the
-color option works correctly. (BZ#616538)

* Previously, ImageMagick could become unresponsive when using the
display command on damaged GIF files. The source code has been revised to
prevent the issue. ImageMagick now produces an error message in the
described scenario. A file selector is now opened so the user can choose
another image to display. (BZ#693989)

* Prior to this update, the convert command did not handle rotated PDF
files correctly. As a consequence, the output was rendered as a portrait
with the content being cropped. With this update, the PDF render geometry
is modified, and the output produced by the convert command is properly
rendered as a landscape. (BZ#694922)

All users of ImageMagick are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. All running
instances of ImageMagick must be restarted for this update to take effect.
