CVE-2019-3832
It was discovered the fix for CVE-2018-19758 (libsndfile) was not complete and still allows a read beyond the limits of a buffer in wav_write_header() function in wav.c.
Does this matter?
Lower severity and a low EPSS score (0.51%). Track it; it rarely justifies an emergency change on its own.
