"The version of Firefox ESR installed on the remote Windows host is prior to 52.7.2. It is, therefore, affected by
multiple vulnerabilities as referenced in the mfsa2018-08 advisory.

  - The libtremor library has the same flaw as CVE-2018-5146. This library is used by Firefox in place of
    libvorbis on Android and ARM platforms. Update: The 52.7.2 source release accidentally did not include
    this patch (the Mozilla-produced 52.7.2 binaries are fine). Anyone building 52.7.2 on ARM should use <a
    href=https://hg.mozilla.org/releases/mozilla-esr52/rev/5cd5586a2f48424a9031a3fa4c782954a9df9a52>revision
    5cd5586a2f48424a9031a3fa4c782954a9df9a52</a> instead of the released source. (CVE-2018-5147)

  - An out of bounds memory write while processing Vorbis audio data was reported through the Pwn2Own contest.
    (CVE-2018-5146)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
