The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3839-1 advisory.

  • 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 function WavpackVerifySingleBlock in open_utils.c in libwavpack.a in WavPack through 5.1.0 allows attackers to cause a denial-of-service (out-of-bounds read and application crash) via a crafted WavPack Lossless Audio file, as demonstrated by wvunpack. (CVE-2018-19841)

Note that Nessus has not tested for these issues but has instead relied only on the applicationโ€™s self-reported version number.
