This version contains a flaw that may permit a malicious user to overwrite
arbitrary files. The issue is triggered when a possible hacker sends a specially
formatted rnfr command. This flaw will permit a remote attacker to overwrite
any file on the system.

*** Nessus solely relied on the banner of the remote server
*** to issue this warning, so it may be a false positive.
