Upgrade Debian:10 libsndfile to version 1.0.28-6+deb10u2 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:10 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.
