CVE-2021-20204

    A heap memory corruption problem (use after free) can be triggered when processing
    maliciously crafted dirfile databases. This degrades the confidentiality,
    integrity and availability of third-party software that uses libgetdata as a library.

0.9.4-1+deb9u1.

We recommend that you upgrade your libgetdata packages.
