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

  • The function WavpackPackInit in pack_utils.c in libwavpack.a in WavPack through 5.1.0 allows attackers to cause a denial-of-service (resource exhaustion caused by an infinite loop) via a crafted wav audio file because WavpackSetConfiguration64 mishandles a sample rate of zero.(CVE-2018-19840)

  • The read_code function in read_words.c in Wavpack before 5.1.0 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted WV file.(CVE-2016-10169)

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.
