H5IMget_image_info(): Make sure to not exceed local array size (#2227)
Malformed hdf5 files may provide more dimensions than the array dim[] in H5IMget_image_info() is able to hold. Check number of elements first by calling H5Sget_simple_extent_dims() with NULL for both 'dims' and 'maxdims' arguments. This will cause the function to return only the number of dimensions. The fix addresse a stack overflow on write. This fixes CVE-2018-17439 / HDFFV-10589 / Bug #2226. Signed-off-by: Egbert Eich <eich@suse.com> Signed-off-by: Egbert Eich <eich@suse.com>
