Integer overflow in Google Chrome before 13.0.782.215 on 32-bit platforms allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors involving uniform arrays.
Integer Overflow or Wraparound 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.
