host is prior to 8.2.5 or 8.3.x prior to 8.3.2P12. It is, therefore,
affected by an unspecified flaw in the handling of certain user input
strings which allow an authenticated user to cause a Denial of Service
(DoS) condition.

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