The OpenBlob function in blob.c in GraphicsMagick before 1.3.24 and ImageMagick allows remote attackers to execute arbitrary code via a | (pipe) character at the start of a filename.
The DrawImage function in MagickCore/draw.c in ImageMagick before 6.9.4-0 and 7.x before 7.0.1-2 makes an incorrect function call in attempting to locate the next token, which allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted file.
The TraceStrokePolygon function in MagickCore/draw.c in ImageMagick before 6.9.4-0 and 7.x before 7.0.1-2 mishandles the relationship between the BezierQuantum value and certain strokes data, which allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted file.
The DrawDashPolygon function in MagickCore/draw.c in ImageMagick before 6.9.4-0 and 7.x before 7.0.1-2 mishandles calculations of certain vertices integer data, which allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted file.
