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.
In ImageMagick before 6.9.7-10, there is a crash (rather than a "width or height exceeds limit" error report) if the image dimensions are too large, as demonstrated by use of the mpc coder.
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.
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.
Memory leak in AcquireVirtualMemory in ImageMagick before 7 allows remote attackers to cause a denial of service (memory consumption) via unspecified vectors.
