"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-2015-8808
    Gustavo Grieco discovered an out of bound read in the
    parsing of GIF files which may cause denial of service.

  - CVE-2016-2317
    Gustavo Grieco discovered a stack-based buffer overflow
    and two heap buffer overflows while processing SVG
    images which may cause denial of service.

  - CVE-2016-2318
    Gustavo Grieco discovered several segmentation faults
    while processing SVG images which may cause denial of
    service.

  - CVE-2016-5240
    Gustavo Grieco discovered an endless loop problem caused
    by negative stroke-dasharray arguments while parsing SVG
    files which may cause denial of service.

  - CVE-2016-7800
    Marco Grassi discovered an unsigned underflow leading to
    heap overflow when parsing 8BIM chunk often attached to
    JPG files which may cause denial of service.

  - 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.

  - CVE-2016-8683

    allocation failure in the PCX coder which may cause
    denial of service.

  - CVE-2016-8684
    Agostino Sarubbo of Gentoo discovered a memory
    allocation failure in the SGI coder which may cause
    denial of service.

  - CVE-2016-9830
