This issue affects the versions of wavpack as shipped with Red Hat Enterprise Linux 8. This flaw has been classified as 'Low' regarding the security impact by the Red Hat Product Security Team.
Red Hat Enterprise Linux versions prior than the mentioned before are not affected as wavpack shipped with those versions doesn't support the file format required.
wavpack application doesn't properly initialize the WaveHeader data structure. When parsing Wave64 file's header without the number of channels information it eventually lead to a 'Division by zero' exception causing DoS. This has a low impact as only the single run from a single user opening the crafted file will be affected.
