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.

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.

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.

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.

In GraphicsMagick 1.3.26, a memory leak vulnerability was found in the function ReadMATImage in coders/mat.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 memory leak vulnerability in the function CloneImage in magick/image.c.

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

GraphicsMagick 1.3.26 has a heap-based buffer overflow vulnerability in the function GetStyleTokens in coders/svg.c:311:12.

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

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

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 ReadMNGImage function in coders/png.c in GraphicsMagick 1.3.26 mishandles large MNG images, leading to an invalid memory read in the SetImageColorCallBack function in magick/image.c.

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 heap overflow in the WriteCMYKImage() function in coders/cmyk.c when processing multiple frames that have non-identical widths.

GraphicsMagick 1.3.26 has a NULL pointer dereference in the WriteMAPImage() function in coders/map.c when processing a non-colormapped image, a different vulnerability than CVE-2017-11638.

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.

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.

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