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/*" /> Let's prevent possible exploits by removing the right to use indirect reads. <policy domain="path" rights="none" pattern="@*" /> Any large image is cached to disk rather than memory: <policy domain="resource" name="area" value="1gb"/> Note, 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). --> <policymap> <!-- <policy domain="system" name="precision" value="6"/> --> <!-- <policy domain="resource" name="temporary-path" value="/tmp"/> --> <policy domain="resource" name="memory" value="48Mib"/> <policy domain="resource" name="map" value="48Mib"/> <!-- <policy domain="resource" name="area" value="1gb"/> --> <!-- <policy domain="resource" name="disk" value="16eb"/> --> <!-- <policy domain="resource" name="file" value="768"/> --> <policy domain="resource" name="thread" value="1"/> <!-- <policy domain="resource" name="throttle" value="0"/> --> <policy domain="resource" name="time" value="300"/> <policy domain="coder" rights="none" pattern="EPHEMERAL" /> <policy domain="coder" rights="none" pattern="HTTPS" /> <policy domain="coder" rights="none" pattern="HTTP" /> <policy domain="coder" rights="none" pattern="URL" /> <policy domain="coder" rights="none" pattern="FTP" /> <policy domain="coder" rights="none" pattern="MVG" /> <policy domain="coder" rights="none" pattern="MSL" /> <policy domain="coder" rights="none" pattern="TEXT" /> <policy domain="coder" rights="none" pattern="LABEL" /> <policy domain="path" rights="none" pattern="@*" /> </policymap>
