Description Andrej Nemec 2018-12-21 09:53:31 UTC 
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.
