Summary
libsndfile vulnerabilities
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)
