CVE-2018-6767
A stack-based buffer over-read in the ParseRiffHeaderConfig function of cli/riff.c file of WavPack 5.1.0 allows a remote attacker to cause a denial-of-service attack or possibly have unspecified other impact via a maliciously crafted RF64 file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
