CVE-2017-8363
The flac_buffer_copy function in flac.c in libsndfile 1.0.28 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted audio file.
Does this matter?
Lower severity and a low EPSS score (3.33%). Track it; it rarely justifies an emergency change on its own.
