remote host is 1.82.  As such, it is potentially affected by a flaw in
how log messages are logged to the Windows Event log.  A remote,
unauthenticated attacker could leverage this issue to cause a denial of
service. 

Note that Nessus did not actually test for the flaw but instead has
relied on the version in War FTP Daemon's banner.");
