"Memory information disclosure in DescribeImage function in
magick/describe.c

GraphicsMagick is vulnerable to a memory information disclosure
vulnerability found in the DescribeImage function of the
magick/describe.c file, because of a heap-based buffer over-read. The
portion of the code containing the vulnerability is responsible for
printing the IPTC Profile information contained in the image. This
vulnerability can be triggered with a specially crafted MIFF file.
There is an out-of-bounds buffer dereference because certain
increments are never checked. (CVE-2017-16353 )

GraphicsMagick 1.3.26 has double free vulnerabilities in the
ReadOneJNGImage() function in coders/png.c (CVE-2017-11139)

In GraphicsMagick there is a stack-based buffer over-read in
WriteWEBPImage in coders/webp.c, related to an incompatibility with
libwebp versions, 0.5.0 and later, that use a different structure
type. (CVE-2017-17913)

In GraphicsMagick 1.3.27, there is an infinite loop and application
hang in the ReadBMPImage function (coders/bmp.c). Remote attackers
could leverage this vulnerability to cause a denial of service via an
image file with a crafted bit-field mask value. (CVE-2018-5685)

The ReadJPEGImage function in coders/jpeg.c in GraphicsMagick 1.3.26
creates a pixel cache before a successful read of a scanline, which
allows remote attackers to cause a denial of service (resource
consumption) via crafted JPEG files. (CVE-2017-11140)

In GraphicsMagick 1.3.26, an allocation failure vulnerability was
found in the function ReadMNGImage in coders/png.c when a small MNG
file has a MEND chunk with a large length value. (CVE-2017-13147)

GraphicsMagick 1.3.26 has a heap overflow in the WriteCMYKImage()
function in coders/cmyk.c when processing multiple frames that have
non-identical widths. (CVE-2017-11643)

GraphicsMagick 1.3.26 has a Memory Leak in the PersistCache function
in magick/pixel_cache.c during writing of Magick Persistent Cache
(MPC) files. (CVE-2017-11641)

In GraphicsMagick there is a heap-based buffer over-read in
ReadMNGImage in coders/png.c, related to accessing one byte before
testing whether a limit has been reached. (CVE-2017-17915)

In GraphicsMagick 1.3.27a, there is a buffer over-read in
ReadPALMImage in coders/palm.c when QuantumDepth is 8.
(CVE-2017-17783)

In GraphicsMagick 1.3.27a, there is a heap-based buffer over-read in
ReadOneJNGImage in coders/png.c, related to oFFs chunk allocation.
(CVE-2017-17782)

coders/wpg.c in GraphicsMagick 1.3.26 allows remote attackers to cause
a denial of service (heap-based buffer overflow and application crash)
or possibly have unspecified other impact via a crafted file, related
to the AcquireCacheNexus function in magick/pixel_cache.c.
(CVE-2017-16669)

In GraphicsMagick there is a heap-based buffer over-read in
ReadNewsProfile in coders/tiff.c, in which LocaleNCompare reads heap
data beyond the allocated region. (CVE-2017-17912)

The ReadOneJNGImage function in coders/png.c in GraphicsMagick 1.3.26
allows remote attackers to cause a denial of service (application
crash) during JNG reading via a zero-length color_image data
structure. (CVE-2017-11102)

GraphicsMagick 1.3.26 has a NULL pointer dereference in the
WritePCLImage() function in coders/pcl.c during writes of monochrome
images. (CVE-2017-11637)

GraphicsMagick 1.3.26 has a heap overflow in the WriteRGBImage()
function in coders/rgb.c when processing multiple frames that have
non-identical widths. (CVE-2017-11636)"
