Package        : libsndfile
CVE ID         : CVE-2021-3246
Debian Bug     : 991496

Andrea Fioraldi discovered a buffer overflow in libsndfile, a library
for reading/writing audio files, which could result in denial of service
or potentially the execution of arbitrary code when processing a
malformed audio file.

For the stable distribution (buster), this problem has been fixed in
version 1.0.28-6+deb10u1.

We recommend that you upgrade your libsndfile packages.

For the detailed security status of libsndfile please refer to
its security tracker page at:
