-------------------------------------
Priority: Major (was: Minor)
> Investigate potential Integer overflows
> ---------------------------------------
>
> Key: DAFFODIL-2411
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2411
> Project: Daffodil
> Issue Type: Bug
> Components: Back End
> Affects Versions: 3.0.0
> Reporter: Josh Adams
> Priority: Major
>
> There are a number of places where we are getting a length of an element or
> an array that could potentially cause an integer overflow to occur.
> For example, all the binary number parsers have a getBitLength funciton that
> returns an int. It is unlikely for a binary number to have such a large
> length that it overflows, but if there were bad data or a bad dfdl:length
> expression, it could definately happen.
> Currently there are calls in many different places that would need range
> checks to prevent this, so it may require some re-architecture to provide a
> clean solution.
