A vulnerability, which was classified as problematic, has been found in HDF5 up to 1.14.6. Affected by this issue is the function H5F_addr_encode_len of the file src/H5Fint.c. The manipulation of the argument pp leads to heap-based buffer overflow. Attacking locally is a requirement. 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.
