Description Sam James archtester gentoo-dev Security 2020-12-28 04:51:09 UTC
Description:
"WavPack 5.3.0 has an out-of-bounds write in WavpackPackSamples in pack_utils.c because of an integer overflow in a malloc argument."

NOTE: the CVE text is misleading; this is still unfixed upstream and affects master too.
