A vulnerability, which was classified as problematic, was found in HDF5 1.14.6. Affected is the function H5O__chunk_protect of the file /src/H5Ochunk.c. The manipulation leads to heap-based buffer overflow. An attack has 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.
