Package : libsndfile
Version : 1.0.28-6+deb10u2
CVE ID : CVE-2021-4156

An issue has been found in libsndfile, a library for reading/writing audio
files.

Using a crafted FLAC file, an attacker could trigger an out-of-bounds read
that would most likely cause a crash but could potentially leak memory
information.

For Debian 10 buster, this problem has been fixed in version
1.0.28-6+deb10u2.

We recommend that you upgrade your libsndfile packages.
