A vulnerability classified as problematic has been found in HDF5 up to 1.14.6. This affects the function H5FS__sinfo_Srialize_Sct_cb of the file src/H5FScache.c. The manipulation of the argument sect leads to heap-based buffer overflow. Local access is required to approach this attack. 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.
