Comment 7 Marco Benatto 2019-08-09 16:07:55 UTC

This issue affects WackPack version as shipped with Red Hat Enterprise Linux 8 and was classified with 'Low' security impact by Red Hat Product Security team.
Red Hat Enterprise Linux 6 and 7 are not affected as WavPack shipped with both system versions doesn't provide support for DSD files.

Comment 9 Marco Benatto 2019-08-09 18:25:31 UTC
When parsing the dsdiff header the wavpack application tries to extract the number of channels the input file has, however this value is not validated before being used. This error can be exploited by crafting a special input file as the channel count will be used later causing a 'division by zero' error leading to DoS. It's a low impact security issue as requires user interaction and only the single run of wavpack will be affected.
