Technical description

The library's failure to check if certain message types support a particular flag, the HDF5 1.8.16 library will cast the structure to an alternative structure and then assign to fields that aren't supported by the message type and the library will write outside the bounds of the heap buffer. This can lead to code execution under the context of the library.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
