The (1) EPHEMERAL, (2) HTTPS, (3) MVG, (4) MSL, (5) TEXT, (6) SHOW, (7) WIN, and (8) PLT coders in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allow remote attackers to execute arbitrary code via shell metacharacters in a crafted image, aka "ImageTragick."
It was discovered that ImageMagick did not properly sanitize certain input before passing it to the delegate functionality. A remote attacker could create a specially crafted image that, when processed by an application using ImageMagick or an unsuspecting user using the ImageMagick utilities, would lead to arbitrary execution of shell commands with the privileges of the user running the application.

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: within the policy map stanza: ... 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
- msl.so to msl.so.bak
- label.so to label.so.bak
