In MP4v2 2.0.0, there is an integer underflow (with resultant memory corruption) when parsing MP4Atom in mp4atom.cpp.
Weakness
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
