Prevent integer overflow when processing covr MPEG4 atoms If the 'chunk_data_size' value is SIZE_MAX, an integer overflow will occur and cause an undersized buffer to be allocated. The following processing then overfills the resulting memory and creates a potentially exploitable condition. Ensure that integer overflow does not occur.
