Description Andrej Nemec 2018-12-21 09:52:31 UTC

The function WavpackPackInit in pack_utils.c in libwavpack.a in WavPack through 5.1.0 allows attackers to cause a denial-of-service (resource exhaustion caused by an infinite loop) via a crafted wav audio file because WavpackSetConfiguration64 mishandles a sample rate of zero.
