The remote host is missing an update to proftpd
announced via advisory FEDORA-2011-0613.
Update Information:
This is an update to the current upstream maintenance release, which addresses a security issue that could affect users of the mod_sql module (not enabled by default).
* A heap-based buffer overflow flaw was found in the way ProFTPD FTP server prepared SQL queries for certain usernames, when the mod_sql module was enabled. A remote, unauthenticated attacker could use this flaw to cause the proftpd daemon to crash or, potentially, to execute arbitrary code with the privileges of the user running 'proftpd' via a specially-crafted username, provided in the authentication dialog.
The update also fixes a CPU spike when handling .ftpaccess files, and handling of SFTP uploads when compression is used.
