Name        : proftpd
Product     : Fedora EPEL 4
Version     : 1.3.2b
Release     : 1.el4
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 behaviour of ProFTPD, but all the
needed scripts to have it run by xinetd instead are included.

Update Information:

This update fixes CVE-2009-3639, in which proftpd's mod_tls, when the
dNSNameRequired TLS option is enabled, does not properly handle a '\0' character
in a domain name in the Subject Alternative Name field of an X.509 client
certificate. This allows remote attackers to bypass intended client-hostname
restrictions via a crafted certificate issued by a legitimate Certification
Authority.    This update to upstream release 1.3.2b also fixes the following
issues recorded in the proftpd bug tracker at bugs.proftpd.org:    - Regression
causing command-line define options not to work (bug 3221)  - Use correct cached
user values with "SQLNegativeCache on" (bug 3282)  - Slower transfers of
multiple small files (bug 3284)  - Support MaxTransfersPerHost,
MaxTransfersPerUser properly (bug 3287)  - Handle symlinks to directories with
trailing slashes properly (bug 3297)
