This issue was patched in RHSA-2020:1581.

NVD Description

Note: Versions mentioned in the description apply only to the upstream wavpack-devel package and not the wavpack-devel package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
