REDHAT-BUG-2441088: Buffer Overflow

Published Feb 19, 2026
·
Updated

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 the practical exploitability of the heap overflow against modern operating systems. Real-world exploitability of this issue in terms of remote-code execution is currently unknown. Version 1.14.4-2 fixes the issue.
