Description Andrej Nemec 2016-06-07 11:14:56 UTC

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.
