CVE-2018-19841
The function WavpackVerifySingleBlock in open_utils.c in libwavpack.a in WavPack through 5.1.0 allows attackers to cause a denial-of-service (out-of-bounds read and application crash) via a crafted WavPack Lossless Audio file, as demonstrated by wvunpack.
Does this matter?
Lower severity and a low EPSS score (2.46%). Track it; it rarely justifies an emergency change on its own.
