Executive Risk Summary
"A heap-based buffer over-read vulnerability exists in the HDF5 Library through version 1.14.3, allowing potential corruption of the instruction pointer. This vulnerability is specific to the H5HL__fl_deserialize function in H5HLcache.c and is distinct from CVE-2024-32613."
Anticipated Attack Path
- 1. Initial Exploitation: An attacker sends a crafted input to the H5HL__fl_deserialize function.
- 2. Buffer Over-read: The function performs a heap-based buffer over-read, potentially corrupting the instruction pointer.
- 3. Arbitrary Code Execution: The attacker may be able to execute arbitrary code due to the corruption of the instruction pointer.
Am I Vulnerable?
- Verify the version of the HDF5 Library in use.
- Check for any signs of exploitation or suspicious activity related to the H5HL__fl_deserialize function.
- Apply the patch to update the HDF5 Library to version 1.14.4 or later.
