There is a memory leak in the function WriteMSLImage of coders/msl.c in ImageMagick 7.0.8-13 Q16, and the function ProcessMSLScript of coders/msl.c in GraphicsMagick before 1.3.31.
The AcquireCacheNexus function in magick/pixel_cache.c in GraphicsMagick before 1.3.28 allows remote attackers to cause a denial of service (heap overwrite) or possibly have unspecified other impact via a crafted image file, because a pixel staging area is not used.
When GraphicsMagick 1.3.25 processes a DPX image (with metadata indicating a large width) in coders/dpx.c, a denial of service (OOM) can occur in ReadDPXImage().
When GraphicsMagick 1.3.25 processes a MATLAB image in coders/mat.c, it can lead to a denial of service (OOM) in ReadMATImage() if the size specified for a MAT Object is larger than the actual amount of data.
When GraphicsMagick 1.3.25 processes an RGB TIFF picture (with metadata indicating a single sample per pixel) in coders/tiff.c, a buffer overflow occurs, related to QuantumTransferMode.
The QuantumTransferMode function in coders/tiff.c in GraphicsMagick 1.3.25 and earlier allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a small samples per pixel value in a CMYKA TIFF file.
The MagickRealloc function in memory.c in Graphicsmagick 1.3.25 allows remote attackers to cause a denial of service (crash) via large dimensions in a jpeg image.
The ReadSCTImage function in coders/sct.c in GraphicsMagick 1.3.25 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted SCT header.
The ReadPCXImage function in coders/pcx.c in GraphicsMagick 1.3.25 allows remote attackers to have unspecified impact via a crafted image, which triggers a memory allocation failure and a "file truncation error for corrupt file."
