[Bug 672328] Re: vsftpd: discloses whether usernames are valid or not

2011-03-03 Thread Andy Wright
userlist_deny This option is examined if userlist_enable is activated. If you set this setting to NO, then users will be denied login unless they are explicitly listed in the file specified by userlist_file. When login is denied, the denial is issued before the user is asked for a password.

This is something you should bring up to the VSFTPD development team as this is not an Ubuntu bug. A VSFTPD mailing list perhaps, or an e-mail to a project code contributor would be appropriate for your concerns. -- You received this bug notification because you are a member of Ubuntu Server

Is your userlist_deny=NO/YES set. Could this be missing or commented out in your configuration? Also, is your local_enable= variable set? The security advisory only addresses disclosure of valid users and does not allow password-less logins. I am sure a patched security update will be provided

This does not allow for non password user authentication. The security, or rather bug in question allows for brute force user name disclosure and therefor a new bug report should be made and this ticket closed as this description states falsely that causes the system to skip asking for a password
