GraphicsMagick 1.3.23 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted SVG file, related to the (1) DrawImage function in magick/render.c, (2) SVGStartElement function in coders/svg.c, and (3) TraceArcPath function in magick/render.c.

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.

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.
(CVE-2016-2317 , CVE-2016-2318 , CVE-2016-5118)

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.
