A vulnerability has been found in HDF5 up to 1.14.6 and classified as problematic. This vulnerability affects the function H5MM_realloc of the file src/H5MM.c. The manipulation of the argument mem leads to double free. 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 calls free() twice on the same memory address.
