Details

It was discovered that libsndfile incorrectly handled memory when parsing
malformed files. A remote attacker could use this issue to cause
libsndfile to crash, resulting in a denial of service. This issue only
applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-9496)

Joshua Rogers discovered that libsndfile incorrectly handled division when
parsing malformed files. A remote attacker could use this issue to cause
libsndfile to crash, resulting in a denial of service. (CVE-2014-9756)

Marco Romano discovered that libsndfile incorrectly handled certain
malformed AIFF files. A remote attacker could use this issue to cause
libsndfile to crash, resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2015-7805)
