    Debian Bug     : 814732 825800 847055
    
    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 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
    
        Agostino Sarubbo of Gentoo discovered a memory 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
    
        Agostino Sarubbo of Gentoo discovered a memory allocation failure in
        MagickRealloc() function which may cause denial of service.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 1.3.20-3+deb8u2.
    
    For the testing distribution (stretch), these problems (with the
    exception of CVE-2016-9830) have been fixed in version 1.3.25-5.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1.3.25-6.
    
    We recommend that you upgrade your graphicsmagick packages.
