Wojciech Purczynski reported two memory leak problems that could be used in a DoS attack: 1) A memoy leak will happen everytime a SIZE command is given, provided that the scoreboard file is not writable. The default installation is *not* vulnerable to this problem; 2) A similar problem existed with the USER command. Every USER command would cause the server to use more memory. Additionally, Przemyslaw Frasunek reported some format string vulnerabilities which have been fixed. SOLUTION It is recommended that all ProFTPd users upgrade to the latest packages.
