| Title | HDFGroup hdf5 v1.14.6 Buffer Overflow |
|---|
| Description | The HDF5 library contains a heap-based buffer overflow vulnerability in the H5T__bit_copy function. This vulnerability occurs during the bitwise copying of data in the HDF5 type conversion logic, where the library attempts to read 1 byte of data beyond the bounds of an allocated heap memory region. This could lead to memory corruption, application crashes, or potential exploitation for arbitrary code execution. |
