CVE-2024-32615

HDF5 Library - H5Znbit.c

HDF Group CVSS 9.8 Updated April 6, 2026

Executive Risk Summary

"A heap-based buffer overflow vulnerability exists in the HDF5 Library through version 1.14.3, specifically in the H5Z__nbit_decompress_one_byte function within H5Znbit.c. This vulnerability can be exploited due to the earlier use of an uninitialized pointer, potentially leading to arbitrary code execution or data corruption."

Anticipated Attack Path

  1. 1. Initial Exploitation: Attacker sends crafted input to the H5Z__nbit_decompress_one_byte function
  2. 2. Buffer Overflow: The function overflows the heap buffer due to the uninitialized pointer
  3. 3. Arbitrary Code Execution: The attacker gains control over the execution flow, potentially leading to code execution or data corruption

Am I Vulnerable?

  • Verify the HDF5 Library version is updated to 1.14.4 or later
  • Monitor system logs for suspicious activity related to the HDF5 Library
  • Implement memory protection mechanisms to mitigate potential exploitation
