Description Marcel Holtmann 2006-05-22 10:09:06 UTC 
When performing bound checks during the parameter processing, we want to use the
real chunk and paramter lengths for bounds instead of the rounded ones. This
prevents us from potentially walking of the end if the chunk length was
miscalculated.

The upstream fix can be found here:
