GraphicsMagick 1.3.26 has a denial of service issue in ReadJNXImage() in coders/jnx.c whereby large amounts of CPU and memory resources may be consumed although the file itself does not support the requests.

GraphicsMagick 1.3.26 has a denial of service issue in ReadXBMImage() in a coders/xbm.c "Read hex image data" version!=10 case that results in the reader not returning; it would cause large amounts of CPU and memory consumption although the crafted file itself does not request it.

GraphicsMagick 1.3.26 has a denial of service issue in ReadXBMImage() in a coders/xbm.c "Read hex image data" version==10 case that results in the reader not returning; it would cause large amounts of CPU and memory consumption although the crafted file itself does not request it.

Off-by-one error in the DrawImage function in magick/render.c in GraphicsMagick 1.3.26 allows remote attackers to cause a denial of service (DrawDashPolygon heap-based buffer over-read and application crash) via a crafted file.

ReadPNMImage in coders/pnm.c in GraphicsMagick 1.3.26 does not ensure the correct number of colors for the XV 332 format, leading to a NULL Pointer Dereference.

ReadRLEImage in coders/rle.c in GraphicsMagick 1.3.26 mishandles RLE headers that specify too few colors, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted file.

ReadDCMImage in coders/dcm.c in GraphicsMagick 1.3.26 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted DICOM image, related to the ability of DCM_ReadNonNativeImages to yield an image list with zero frames.

GraphicsMagick 1.3.26 allows remote attackers to cause a denial of service (excessive memory allocation) because of an integer underflow in ReadPICTImage in coders/pict.c.

ReadOneJNGImage in coders/png.c in GraphicsMagick 1.3.26 has a use-after-free issue when the height or width is zero, related to ReadJNGImage.

In ReadOneJNGImage in coders/png.c in GraphicsMagick 1.3.26, a Null Pointer Dereference occurs while transferring JPEG scanlines, related to a PixelPacket pointer.

GraphicsMagick: Heap based buffer over-write in DescribeImage() function of the magick/describe.c or magick/image.c

GraphicsMagick 1.3.26 is vulnerable to a heap-based buffer overflow vulnerability found in the "Display visual image directory" feature of the DescribeImage() function of the magick/describe.c file. One possible way to trigger the vulnerability is to run the identify command on a specially crafted MIFF format file with the verbose flag.

GraphicsMagick: memory information disclosure in DescribeImage function in magick/describe.c

GraphicsMagick 1.3.26 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.

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.

ReadRGBImage in coders/rgb.c in GraphicsMagick 1.3.26 has a magick/import.c ImportRGBQuantumType heap-based buffer over-read via a crafted file.

WriteOnePNGImage in coders/png.c in GraphicsMagick 1.3.26 has a heap-based buffer over-read via a crafted file.

ReadCMYKImage in coders/cmyk.c in GraphicsMagick 1.3.26 has a magick/import.c ImportCMYKQuantumType heap-based buffer over-read via a crafted file.

ReadGRAYImage in coders/gray.c in GraphicsMagick 1.3.26 has a magick/import.c ImportGrayQuantumType heap-based buffer over-read via a crafted file.

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

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

In GraphicsMagick 1.4 snapshot-20171217 Q8, there is a heap-based buffer over-read in ReadNewsProfile in coders/tiff.c, in which LocaleNCompare reads heap data beyond the allocated region.
