Kerentanan Buffer Underwrite ('Buffer Underflow') pada hdfgroup hdf5. Skor CVSS 3.1 6.5 (Medium) menurut NVD.

Deskripsi (NVD)

HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If `H5Iget_name` is invoked on a group id with `0` for the size parameter, it will underflow when trying to place a null terminator in the buffer. This can occur if `H5Iget_name` is invoked in a way where `size` can be forced to zero, and there is important data before the `name` buffer.
