Process crash via scale-offset buffer overrun
Published May 9, 2024 · Updated Feb 13, 2025
Buffer overflow in HDF5 1.14.3 and earlier allows attackers to crash a parsing process via malformed scale-offset-encoded HDF5 files. The H5Z__filter_scaleoffset filter processes malformed dataset data without adequate bounds checking, corrupting the instruction pointer. Triggering the flaw requires an application or service to parse an attacker-controlled HDF5 file; the vendor test demonstrates a crash, while public evidence does not demonstrate code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
