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.
ImageMagick before 7.0.5-2 and GraphicsMagick before 1.3.24 use uninitialized memory in the RLE decoder, allowing an attacker to leak sensitive information from process memory space, as demonstrated by remote attacks against ImageMagick code in a long-running server process that converts image data on behalf of multiple users. This is caused by a missing initialization step in the ReadRLEImage function in coders/rle.c.
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 DrawDashPolygon function in magick/render.c in GraphicsMagick before 1.3.24 and the SVG renderer in ImageMagick allow remote attackers to cause a denial of service (infinite loop) by converting a circularly defined SVG file.
Heap-based buffer overflow in the EscapeParenthesis function in GraphicsMagick before 1.3.25 allows remote attackers to have unspecified impact via unknown vectors.
The Utah RLE reader in GraphicsMagick before 1.3.25 allows remote attackers to cause a denial of service (CPU consumption or large memory allocations) via vectors involving the header information and the file size.
Integer underflow in the parse8BIM function in coders/meta.c in GraphicsMagick 1.3.25 and earlier allows remote attackers to cause a denial of service (application crash) via a crafted 8BIM chunk, which triggers a heap-based buffer overflow.
magick/render.c in GraphicsMagick before 1.3.24 allows remote attackers to cause a denial of service (arithmetic exception and application crash) via a crafted svg file.
