"The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by
multiple vulnerabilities as referenced in the K000137093 advisory.

  - Calling Buffer.fill() or Buffer.alloc() with some parameters can lead to a hang which could result in a
    Denial of Service. In order to address this vulnerability, the implementations of Buffer.alloc() and
    Buffer.fill() were updated so that they zero fill instead of hanging in these cases. All versions of
    Node.js 6.x (LTS Boron), 8.x (LTS Carbon), and 9.x are vulnerable. All versions of Node.js 10.x
    (Current) are NOT vulnerable. (CVE-2018-7167)

  - In all versions of Node.js prior to 6.14.4, 8.11.4 and 10.9.0 when used with UCS-2 encoding (recognized by
    Node.js under the names `'ucs2'`, `'ucs-2'`, `'utf16le'` and `'utf-16le'`), `Buffer#write()` can be abused
    to write outside of the bounds of a single `Buffer`. Writes that start from the second-to-last position of
    a buffer cause a miscalculation of the maximum length of the input bytes to be written. (CVE-2018-12115)

  - Node.js: All versions prior to Node.js 6.15.0 and 8.14.0: HTTP request splitting: If Node.js can be
    convinced to use unsanitized user-provided Unicode data for the `path` option of an HTTP request, then
    data can be provided which will trigger a second, unexpected, and user-defined HTTP request to made to the
    same server. (CVE-2018-12116)

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