Originalnachricht

Name        : proftpd
Product : Fedora 18
Version : 1.3.4d
Release : 4.fc18
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 update addresses an issue with mod_sftp and mod_sftp_pam in which a
malicious client could cause the server to make extremely large memory requests and potentially crash.
