| Description: | Summary:
The remote host is missing an update for the Debian 'graphicsmagick' package(s) announced via the DSA-3746-1 advisory.
Vulnerability Insight:
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.
