"The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-2828 advisory.

  - The bark_noise_hybridmp function in psy.c in Xiph.Org libvorbis 1.3.5 allows remote attackers to cause a
    denial of service (out-of-bounds access and application crash) or possibly have unspecified other impact
    via a crafted mp4 file. (CVE-2017-14160)

  - mapping0_forward in mapping0.c in Xiph.Org libvorbis 1.3.6 does not validate the number of channels, which
    allows remote attackers to cause a denial of service (heap-based buffer overflow or over-read) or possibly
    have unspecified other impact via a crafted file. (CVE-2018-10392)

  - bark_noise_hybridmp in psy.c in Xiph.Org libvorbis 1.3.6 has a stack-based buffer over-read.
    (CVE-2018-10393)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
