Integer overflow in jas_image.c in JasPer before 1.900.25 allows remote attackers to cause a denial of service (application crash) via a crafted file.
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.
