"The version of Core FTP installed on the remote host is prior to 2.2
build 1769 (2.2.1768.0).  It is, therefore, affected by multiple buffer
overflow vulnerabilities because user-supplied input is not properly
validated when handling directory names.  A remote attacker could
potentially exploit this issue with specially crafted directory names,
resulting in a denial of service or code execution subject to the user's
privileges. 

Note that the fix for this issue is version 2.2 Build 1769 while the
actual file version is 2.2.1768.");
