"The version of NetApp Clustered Data ONTAP running on the remote
host is 8.x prior to 8.3.2P8 or 9.x prior to 9.0P2. It is, therefore,
affected by a heap overflow vulnerability in the SMB implementation
that allows a remote unauthenticated attacker to cause a denial of
service disruption or execute arbitrary code. ONTAP 9.1 and higher
are unaffected.

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