Integer overflow in MagickCore/profile.c in ImageMagick before 7.0.2-1 allows remote attackers to cause a denial of service (segmentation fault) or possibly execute arbitrary code via vectors involving the offset variable.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
