WritePNMImage in coders/pnm.c in GraphicsMagick 1.3.26 allows remote attackers to cause a denial of service (bit_stream.c MagickBitStreamMSBWrite heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file.Show less

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.Show less

The DrawImage function in magick/render.c in GraphicsMagick 1.3.26 does not properly look for pop keywords that are associated with push keywords, which allows remote attackers to cause a denial of service (negative strncpy and application crash) or possibly have unspecified other impact via a crafted file.Show less

The ReadWPGImage function in coders/wpg.c in GraphicsMagick 1.3.26 does not properly validate colormapped images, which allows remote attackers to cause a denial of service (ImportIndexQuantumType invalid write and application crash) or possibly have unspecified other impact via a malformed WPG image.Show less

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.Show less

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.Show less

ReadGIFImage in coders/gif.c in ImageMagick 7.0.6-1 and GraphicsMagick 1.3.26 leaves the palette uninitialized when processing a GIF file that has neither a global nor local palette. If the affected product is used as a library loaded into a process that operates on interesting data, this data sometimes can be leaked via the uninitialized palette.Show less

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.Show less

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.Show less

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.Show less

The ReadSUNImage function in coders/sun.c in GraphicsMagick 1.3.26 has an issue where memory allocation is excessive because it depends only on a length field in a header. This may lead to remote denial of service in the MagickMalloc function in magick/memory.c.Show less
