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.
