A vulnerability was found in HDF5 up to 1.14.6. It has been declared as problematic. Affected by this vulnerability is the function H5O_msg_flush of the file src/H5Omessage.c. The manipulation of the argument oh leads to heap-based buffer overflow. The attack needs to be approached locally. 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.
