"oftpd is designed to be as secure as an anonymous FTP server can
|
|
possibly be. It runs as non-root for most of the time, and uses the
|
|
Unix chroot() command to hide most of the systems directories from
|
|
external users - they cannot change into them even if the server is
|
|
totally compromised! It contains its own directory change code, so that
|
|
it can run efficiently as a threaded server, and its own directory
|
|
listing code (most FTP servers execute the system "ls" command to list
|
|
files)."

|
|
Issuing a port command with a number higher than 255 causes the server
|
|
to crash. The port command may be issued before any authentication
|
|
takes place, meaning the attacker does not need to know a valid
|
|
username and password in order to exploit this vulnerability.
