CVE-2018-19840 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.30% chance of exploitation in the next 30 days.
