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

Several vulnerabilities have been discovered in GraphicsMagick, a set of command-line applications to manipulate image files, which could result in denial of service or the execution of arbitrary code if malformed image files are processed.

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)
