GraphicsMagick 1.3.26 has a segmentation violation in the WriteMAPImage() function in coders/map.c when processing a non-colormapped image, a different vulnerability than CVE-2017-11642.

The WriteOnePNGImage function in coders/png.c in GraphicsMagick 1.3.26 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted file, because the program's actual control flow was inconsistent with its indentation. This resulted in a logging statement executing outside of a loop, and consequently using an invalid array index corresponding to the loop's exit condition.

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

The ReadWMFImage function in coders/wmf.c in GraphicsMagick 1.3.26 has a use-after-free issue for data associated with exception reporting.

The ReadSUNImage function in coders/sun.c in GraphicsMagick 1.3.26 has a colormap heap-based buffer over-read.

GraphicsMagick 1.3.26 has a heap-based buffer overflow vulnerability in the function GetStyleTokens in coders/svg.c:314:12.

Buffer overflow in the MVG and SVG rendering code in GraphicsMagick 1.3.24 allows remote attackers to have unspecified impact via unknown vectors. Note: This vulnerability exists due to an incomplete patch for CVE-2016-2317.

GraphicsMagick 1.3.26 has a NULL pointer dereference vulnerability in the function SVGStartElement in coders/svg.c.

GraphicsMagick: Memory leak in CloneImage function in magick/image.c

GraphicsMagick 1.3.26 has a memory leak vulnerability in the function CloneImage in magick/image.c.

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.

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.

There are lots of memory leaks in the GMCommand function in magick/command.c in GraphicsMagick 1.3.26 that will lead to a remote denial of service attack.

There is an invalid free in the MagickFree function in magick/memory.c in GraphicsMagick 1.3.26 that will lead to a remote denial of service attack.

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.

The ReadMNGImage function in coders/png.c in GraphicsMagick 1.3.26 has an out-of-order CloseBlob call, resulting in a use-after-free via a crafted file.

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.

A memory allocation failure was discovered in the ReadPNMImage function in coders/pnm.c in GraphicsMagick 1.3.26. The vulnerability causes a big memory allocation, which may lead to remote denial of service in the MagickRealloc function in magick/memory.c.

The ReadJNGImage and ReadOneJNGImage functions in coders/png.c in GraphicsMagick 1.3.26 do not properly manage image pointers after certain error conditions, which allows remote attackers to conduct use-after-free attacks via a crafted file, related to a ReadMNGImage out-of-order CloseBlob call. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-11403.

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.

magick/render.c in GraphicsMagick before 1.3.24 allows remote attackers to cause a denial of service (arithmetic exception and application crash) via a crafted svg file.
