a vulnerability as referenced in the mfsa2017-04 advisory.

  - The cache directory on the local file system is set to be world writable. Firefox defaults to extracting
    libraries from this cache. This allows for the possibility of an installed malicious application or tools
    with write access to the file system to replace files used by Firefox with their own versions.
    (CVE-2017-5397)

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