HDF5 is software for managing data. Prior to version 1.14.4-2, an attacker who can control an h5 file parsed by HDF5 can trigger a write-based heap buffer overflow condition. This can lead to a denial-of-service condition, and potentially further issues such as remote code execution depending on...
