According to the version of the wavpack package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  • WavpackSetConfiguration64 in pack_utils.c in libwavpack.a in WavPack through 5.1.0 has a β€˜Conditional jump or move depends on uninitialised value’ condition, which might allow attackers to cause a denial of service (application crash) via a DFF file that lacks valid sample-rate data.(CVE-2019-11498)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
