"cvedetails.com reports :

CVE-2019-7175: In ImageMagick before 7.0.8-25, some memory leaks exist
in DecodeImage in coders/pcd.c.

CVE-2019-7395: In ImageMagick before 7.0.8-25, a memory leak exists in
WritePSDChannel in coders/psd.c.

CVE-2019-7396: In ImageMagick before 7.0.8-25, a memory leak exists in
ReadSIXELImage in coders/sixel.c.

CVE-2019-7397: In ImageMagick before 7.0.8-25 and GraphicsMagick
through 1.3.31, several memory leaks exist in WritePDFImage in
coders/pdf.c.

CVE-2019-7398: In ImageMagick before 7.0.8-25, a memory leak exists in
WriteDIBImage in coders/dib.c.

CVE-2019-9956: In ImageMagick 7.0.8-35 Q16, there is a stack-based
buffer overflow in the function PopHexPixel of coders/ps.c, which
allows an attacker to cause a denial of service or code execution via
a crafted image file.

CVE-2019-10131: An off-by-one read vulnerability was discovered in
ImageMagick before version 7.0.7-28 in the formatIPTCfromBuffer
function in coders/meta.c. A local attacker may use this flaw to read
beyond the end of the buffer or to crash the program.

CVE-2019-10649: In ImageMagick 7.0.8-36 Q16, there is a memory leak in
the function SVGKeyValuePairs of coders/svg.c, which allows an
attacker to cause a denial of service via a crafted image file.

CVE-2019-10650: In ImageMagick 7.0.8-36 Q16, there is a heap-based
buffer over-read in the function WriteTIFFImage of coders/tiff.c,
which allows an attacker to cause a denial of service or information
disclosure via a crafted image file.

CVE-2019-10714: LocaleLowercase in MagickCore/locale.c in ImageMagick
before 7.0.8-32 allows out-of-bounds access, leading to a SIGSEGV.

CVE-2019-11470: The cineon parsing component in ImageMagick 7.0.8-26
Q16 allows attackers to cause a denial-of-service (uncontrolled
resource consumption) by crafting a Cineon image with an incorrect
claimed image size. This occurs because ReadCINImage in coders/cin.c
lacks a check for insufficient image data in a file.

CVE-2019-11472: ReadXWDImage in coders/xwd.c in the XWD image parsing
component of ImageMagick 7.0.8-41 Q16 allows attackers to cause a
denial-of-service (divide-by-zero error) by crafting an XWD image file
in which the header indicates neither LSB first nor MSB first.

CVE-2019-11597: In ImageMagick 7.0.8-43 Q16, there is a heap-based
buffer over-read in the function WriteTIFFImage of coders/tiff.c,
which allows an attacker to cause a denial of service or possibly
information disclosure via a crafted image file.

CVE-2019-11598: In ImageMagick 7.0.8-40 Q16, there is a heap-based
buffer over-read in the function WritePNMImage of coders/pnm.c, which
allows an attacker to cause a denial of service or possibly
information disclosure via a crafted image file. This is related to
SetGrayscaleImage in MagickCore/quantize.c."
