It was discovered that GraphicsMagick did not properly sanitize certain input before using it to invoke processes. A remote attacker could create a specially crafted image that, when processed by an application using GraphicsMagick or an unsuspecting user using the GraphicsMagick utilities, would lead to arbitrary execution of shell commands with the privileges of the user running the application.
(CVE-2016-5118)

Vulnerabilities in GraphicsMagick's SVG processing code were discovered, resulting in memory corruption and, potentially, execution of arbitrary code, a denial of service, or an application crash.

Several security vulnerabilities were discovered in graphicsmagick a tool to manipulate image files.

GraphicsMagick is a fork of ImageMagick and also affected by vulnerabilities collectively known as ImageTragick, that are the consequence of lack of sanitization of untrusted input. An attacker with control on the image input could, with the privileges of the user running the application, execute code (CVE-2016-3714), make HTTP GET or FTP requests (CVE-2016-3718), or delete (CVE-2016-3715), move (CVE-2016-3716), or read (CVE-2016-3717) local files.

To address these concerns the following changes have been made :

1. Remove automatic detection/execution of MVG based on file header or file extension.

2. Remove the ability to cause an input file to be deleted based on a filename specification.

3. Improve the safety of delegates.mgk by removing gnuplot support, removing manual page support, and by adding -dSAFER to all ghostscript invocations.

4. Sanity check the MVG image primitive filename argument to assure that 'magick:' prefix strings will not be interpreted. Please note that this patch will break intentional uses of magick prefix strings in MVG and so some MVG scripts may fail. We will search for a more flexible solution.

In addition the following issues have been fixed :

CVE-2015-8808 Assure that GIF decoder does not use unitialized data and cause an out-of-bound read.

CVE-2016-2317 and CVE-2016-2318 Vulnerabilities that allow to read or write outside memory bounds (heap, stack) as well as some NULL pointer derreferences to cause a denial of service when parsing SVG files.

For Debian 7 'Wheezy', these problems have been fixed in version 1.3.16-1.1+deb7u1.

We recommend that you upgrade your graphicsmagick packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several vulnerabilities have been discovered in GraphicsMagick, a collection of image processing tool, which can cause denial of service attacks, remote file deletion, and remote command execution.

This security update removes the full support of PLT/Gnuplot decoder to prevent Gnuplot-shell based shell exploits for fixing the CVE-2016-3714 vulnerability.

The undocumented 'TMP' magick prefix no longer removes the argument file after it has been read for fixing the CVE-2016-3715 vulnerability. Since the 'TMP' feature was originally implemented, GraphicsMagick added a temporary file management subsystem which assures that temporary files are removed so this feature is not needed.

Remove support for reading input from a shell command, or writing output to a shell command, by prefixing the specified filename (containing the command) with a '|' for fixing the CVE-2016-5118 vulnerability.

  - CVE-2016-7996     Moshe Kaplan discovered that there is no check that the     provided colormap is not larger than 256 entries in the     WPG reader which may cause denial of service.

  - CVE-2016-7997     Moshe Kaplan discovered that an assertion is thrown for     some files in the WPG reader due to a logic error which     may cause denial of service.

  - CVE-2016-8682     Agostino Sarubbo of Gentoo discovered a stack buffer     read overflow while reading the SCT header which may     cause denial of service.
