USN-5409-1

It was discovered that libsndfile was incorrectly performing memory management operations and incorrectly using buffers 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.
