WS_FTP earlier than 6.1.1.  Such versions are reportedly affected by
multiple vulnerabilities :

  - Improper handling of UDP packets within the FTP log 
    server may allow an attacker to crash the affected 
    service. (CVE-2008-0608)

  - There is a buffer overflow vulnerability in the SSH 
    Server service that can be triggered when handling 
    arguments to the 'opendir' command. (CVE-2008-0590)

  - An attacker can exploit a vulnerability in the
    'FTPLogServer/LogViewer.asp' script to gain access to
    the log viewing interface. (CVE-2008-5692)" );
