Name        : proftpd
Product     : Fedora 14
Version     : 1.3.3d
Release     : 1.fc14
URL         : http://www.proftpd.org/
Summary     : Flexible, stable and highly-configurable FTP server
Description :
ProFTPD is an enhanced FTP server with a focus toward simplicity, security,
and ease of configuration. It features a very Apache-like configuration
syntax, and a highly customizable server infrastructure, including support for
multiple 'virtual' FTP servers, anonymous FTP, and permission-based directory
visibility.

This package defaults to the standalone behavior of ProFTPD, but all the
needed scripts to have it run by xinetd instead are included.

--------------------------------------------------------------------------------
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.
