In ImageMagick before 6.9.9-3 and 7.x before 7.0.6-3, there is a missing NULL check in the ReadMATImage function in coders/mat.c, leading to a denial of service (assertion failure and application exit) in the DestroyImageInfo function in MagickCore/image.c.

In ImageMagick before 6.9.9-1 and 7.x before 7.0.6-2, the ReadOnePNGImage function in coders/png.c allows remote attackers to cause a denial of service (application hang in LockSemaphoreInfo) via a PNG file with a width equal to MAGICK_WIDTH_LIMIT.

In ImageMagick before 6.9.9-4 and 7.x before 7.0.6-4, a crafted file could trigger a memory leak in ReadOnePNGImage in coders/png.c.

In ImageMagick before 6.9.9-0 and 7.x before 7.0.6-1, a crafted PNG file could trigger a crash because there was an insufficient check for short files.

In ImageMagick before 6.9.9-0 and 7.x before 7.0.6-1, the ReadOneMNGImage function in coders/png.c has an out-of-bounds read with the MNG CLIP chunk.

In ImageMagick 7.0.6-6 and GraphicsMagick 1.3.26, a heap-based buffer over-read was found in the function SFWScan in coders/sfw.c, which allows attackers to cause a denial of service via a crafted file.

In ImageMagick 7.0.6-6, a memory leak vulnerability was found in the function WriteOneJNGImage in coders/png.c, which allows attackers to cause a denial of service (WriteJNGImage memory consumption) via a crafted file.

In ImageMagick 7.0.6-6, a memory leak vulnerability was found in the function formatIPTC in coders/meta.c, which allows attackers to cause a denial of service (WriteMETAImage memory consumption) via a crafted file.

In ImageMagick 7.0.6-6, a memory leak vulnerability was found in the function WritePCXImage in coders/pcx.c, which allows attackers to cause a denial of service via a crafted file.

The ProcessMSLScript function in coders/msl.c in ImageMagick before 6.9.9-5 and 7.x before 7.0.6-5 allows remote attackers to cause a denial of service (memory leak) via a crafted file, related to the WriteMSLImage function.
