Doc Type: Bug Fix
Doc Text:
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.

Description Andrej Nemec 2016-05-03 10:53:53 UTC
A vulnerability was found in ImageMagick. It is possible to delete files by using ImageMagick's 'ephemeral' pseudo protocol which deletes files after reading.

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:


Red Hat Enterprise Linux 5

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