"The version of F5 Networks BIG-IP installed on the remote host is prior to 14.0.0 / 15.0.0. It is, therefore, affected
by a vulnerability as referenced in the K21462542 advisory.

  - While parsing an IPAddressFamily extension in an X.509 certificate, it is possible to do a one-byte
    overread. This would result in an incorrect text display of the certificate. This bug has been present
    since 2006 and is present in all versions of OpenSSL before 1.0.2m and 1.1.0g. (CVE-2017-3735)

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