How to fix?

Upgrade Debian:9 libsndfile to version 1.0.27-3+deb9u3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libsndfile package and not the libsndfile package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

An out-of-bounds read flaw was found in libsndfile's FLAC codec functionality. An attacker who is able to submit a specially crafted file (via tricking a user to open or otherwise) to an application linked with libsndfile and using the FLAC codec, could trigger an out-of-bounds read that would most likely cause a crash but could potentially leak memory information that could be used in further exploitation of other flaws.
