A vulnerability, which was classified as problematic, was found in HDF5 up to 1.14.6. This affects the function H5HL__fl_deserialize of the file src/H5HLcache.c. The manipulation of the argument free_block leads to heap-based buffer overflow. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
The product writes data past the end, or before the beginning, of the intended buffer.
