vulnerabilities as referenced in the SSA:2022-191-01 advisory.

  - An out of bounds read was found in Wavpack 5.4.0 in processing *.WAV files. This issue triggered in
    function WavpackPackSamples of file src/pack_utils.c, tainted variable cnt is too large, that makes
    pointer sptr read beyond heap bound. (CVE-2021-44269)
