CentOS 6 / 7 : ImageMagick (CESA-2016:0726) (ImageTragick)

high Nessus Plugin ID 91020

Language:

Synopsis

The remote CentOS host is missing one or more security updates.

Description

An update for ImageMagick is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

ImageMagick is an image display and manipulation tool for the X Window System that can read and write multiple image formats.

Security Fix(es) :

* 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.
(CVE-2016-3714)

* 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, move, or disclose the contents of arbitrary files. (CVE-2016-3715, CVE-2016-3716, CVE-2016-3717)

* A server-side request forgery flaw was discovered in the way ImageMagick processed certain images. A remote attacker could exploit this flaw to mislead an application using ImageMagick or an unsuspecting user using the ImageMagick utilities into, for example, performing HTTP(S) requests or opening FTP sessions via specially crafted images. (CVE-2016-3718)

Note: This update contains an updated /etc/ImageMagick/policy.xml file that disables the EPHEMERAL, HTTPS, HTTP, URL, FTP, MVG, MSL, TEXT, and LABEL coders. If you experience any problems after the update, it may be necessary to manually adjust the policy.xml file to match your requirements. Please take additional precautions to ensure that your applications using the ImageMagick library do not process malicious or untrusted files before doing so.

Solution

Update the affected imagemagick packages.
