libsndfile vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in libsndfile.

Software Description:
- libsndfile: Library for reading/writing audio files

Details:

It was discovered that libsndfile incorrectly handled memory when executing
its FLAC codec. If a user or automated system were tricked into processing
a specially crafted sound file, an attacker could possibly use this issue
to cause a denial of service or obtain sensitive information.
(CVE-2021-4156)

It was discovered that libsndfile incorrectly handled certain malformed
OggVorbis files. An attacker could possibly use this issue to cause
libsndfile to crash, resulting in a denial of service. (CVE-2024-50612)
