This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Heap-based buffer overflow in the GetWavHeader function in generic/jkSoundFile.c in the Snack Sound Toolkit, as used in WaveSurfer 1.8.8p4, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large chunk size in a WAV file.
