Details can be found under the resolve tab at https://access.redhat.com/security/vulnerabilities/2296071

Red Hat Enterprise Linux 6 and 7
================================

As a workaround the /etc/ImageMagick/policy.xml file can be edited to disable processing of MVG, HTTPS, HTTP, URL, FTP, EPHEMERAL, MSL, LABEL, TEXT,
SHOW, WIN and PLT commands within image files, simply add the following lines:

<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="coder" rights="none" pattern="SHOW" />
<policy domain="coder" rights="none" pattern="WIN" />
<policy domain="coder" rights="none" pattern="PLT" />
<policy domain="path" rights="none" pattern="@*" />

within the policy map stanza:

<policymap>
...
</policymap>


Red Hat Enterprise Linux 5
==========================

In the following folders:
/usr/lib64/ImageMagick-6.2.8/modules-Q16/coders/ (64bit package)
or
/usr/lib/ImageMagick-6.2.8/modules-Q16/coders/ (32bit package)

Rename the following files:
* mvg.so to mvg.so.bak

* label.so to label.so.bak
