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 6.9.8-8 and 7.x before 7.0.5-9, the ReadJP2Image function in coders/jp2.c does not properly validate the channel geometry, leading to a crash.

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 6.9.8-5 and 7.x before 7.0.5-6, there is a memory leak in the ReadMATImage function in coders/mat.c.

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 before 6.9.7-6 and 7.x before 7.0.4-6, the ReadMATImage function in coders/mat.c uses uninitialized data, which might allow remote attackers to obtain sensitive information from process memory.

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.

The ReadMATImage function in coders/mat.c in ImageMagick through 6.9.9-3 and 7.x through 7.0.6-3 has memory leaks involving the quantum_info and clone_info data structures.
