CVE-2016-82001 - When scanning a Mac OS X host using credentials, a
malicious local user could trick Nessus into executing an arbitrary
command as root, thus resulting into a privilege-escalation
Note that the following CVSSv2 score reflects the risk to the host
being scanned by Nessus, not the system hosting Nessus. Since Nessus
is being used as an exploit for a target host, the score does not
reflect a threat to Nessus. As such, it is not being listed as the
primary CVSSv2 score for this advisory.
CVSSv2 Base/Temporal: 7.6 / 4.9
Nessus Folder Name Stored Scripting
Charlie Svensson reported that Nessus will render script code for
folder names. This was also found internally but filed as a regular
bug, as the folder names only render to the user who renamed them.
Since folder names are not seen across user accounts, this does not
pose any risk. Regardless, this issue has been fixed." 
The vendor advises users should upgrade to the latest
version of Tenable Nessus and Nessus Enterprise to resolve these
