"The version of F5 Networks BIG-IP installed on the remote host is prior to 15.1.10.8 / 16.1.6.1 / 17.1.3 / 17.5.1.2. It
is, therefore, affected by a vulnerability as referenced in the K000149130 advisory.

    The c-ares function `ares_parse_naptr_reply()`, which is used for parsing NAPTR responses, could be
    triggered to read memory outside of the given input buffer if the passed in DNS response packet was
    crafted in a particular way.(CVE-2017-1000381)

Tenable has extracted the preceding description block directly from the F5 Networks BIG-IP security advisory.

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