Fedora EPEL Update Notification
FEDORA-EPEL-2011-0102

--------------------------------------------------------------------------------
Name : proftpd
Product : Fedora EPEL 5
Version : 1.3.3d
Release : 1.el5
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.
