Various security issues were discovered in Graphicsmagick, a collection
of image processing tools.

CVE-2017-18219
    An allocation failure vulnerability was found in the function
    ReadOnePNGImage in coders/png.c, which allows attackers to cause a
    denial of service via a crafted file that triggers an attempt at a
    large png_pixels array allocation.

CVE-2017-18220
    The ReadOneJNGImage and ReadJNGImage functions in coders/png.c allow
    remote attackers to cause a denial of service or possibly have
    unspecified other impact via a crafted file, a related issue
    to CVE-2017-11403.

CVE-2017-18229
    An allocation failure vulnerability was found in the function
    ReadTIFFImage in coders/tiff.c, which allows attackers to cause a
    denial of service via a crafted file, because file size is not
    properly used to restrict scanline, strip, and tile allocations.

CVE-2017-18230
    A NULL pointer dereference vulnerability was found in the function
    ReadCINEONImage in coders/cineon.c, which allows attackers to cause
    a denial of service via a crafted file.

CVE-2017-18231
    A NULL pointer dereference vulnerability was found in the function
    ReadEnhMetaFile in coders/emf.c, which allows attackers to cause
    a denial of service via a crafted file.

CVE-2018-9018
    There is a divide-by-zero error in the ReadMNGImage function of
    coders/png.c. Remote attackers could leverage this vulnerability to
    cause a crash and denial of service via a crafted mng file.

For Debian 7 "Wheezy", these problems have been fixed in version
1.3.16-1.1+deb7u19.
