Описание
The EPHEMERAL coder in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allows remote attackers to delete arbitrary files via a crafted image.
It was discovered that certain ImageMagick coders and pseudo-protocols did not properly prevent security sensitive operations when processing specially crafted images. 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 allow the attacker to delete arbitrary files.

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
