+ImageMagick Cookbook
+=========
+
+There were two recent ImageMagick-related vulnerabilities:
+
+* CVE-2016-5118
+* CVE-2016-3714
+
+This cookbook installs ImageMagick 6.9.0.3-r1 (available on the latest Gentoo 12.11 stack) and a policy.xml file. 
+
+The 6.9.0.3-r1 ebuild includes backported patches to address the popen vulnerability in CVE-2016-5118.
+
+The policy.xml file is the policy recommended in https://www.imagemagick.org/discourse-server/viewtopic.php?f=4&p=132726&sid=6b961f8b680a0c18189de528bd53504a#p132726 to address CVE-2016-3714.
+
+To use this recipe, add the line
+
+```
+include_recipe 'imagemagick'
+```
+
+to `cookbooks/main/recipes/default.rb`.

+  Configure ImageMagick policies.
+
+  Domains include system, delegate, coder, filter, path, or resource.
+
+  Rights include none, read, write, and execute.  Use | to combine them,
+  for example: "read | write" to permit read from, or write to, a path.
+
+  Use a glob expression as a pattern.
+
+  Suppose we do not want users to process MPEG video images:
+
+    <policy domain="delegate" rights="none" pattern="mpeg:decode" />
+
+  Here we do not want users reading images from HTTP:
+
+    <policy domain="coder" rights="none" pattern="HTTP" />
+
+  Lets prevent users from executing any image filters:
+
+    <policy domain="filter" rights="none" pattern="*" />
+
+  The /repository file system is restricted to read only.  We use a glob
+  expression to match all paths that start with /repository:
+  
+    <policy domain="path" rights="read" pattern="/repository/*" />
+
+  Any large image is cached to disk rather than memory:
+
+    <policy domain="resource" name="area" value="1GB"/>
+
+  Define arguments for the memory, map, area, width, height, and disk resources
+  with SI prefixes (.e.g 100MB).  In addition, resource policies are maximums
+  for each instance of ImageMagick (e.g. policy memory limit 1GB, -limit 2GB
+  exceeds policy maximum so memory limit is 1GB).
