Name        : proftpd
Product     : Fedora 14
Version     : 1.3.3c
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

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 two security issues that can be exploited by malicious users to manipulate certain data and compromise a vulnerable system.

* A logic error in the code for processing user input containing the Telnet IAC (Interpret As Command) escape sequence can be exploited to cause a stack-based buffer overflow by sending specially crafted input to the FTP or FTPS service. Successful exploitation may allow execution of arbitrary code. This has been assigned the name CVE-2010-4221. More details can be found at http://bugs.proftpd.org/show_bug.cgi?id=3521

* An input validation error within the "mod_site_misc" module can be exploited to e.g. create and delete directories, create symlinks, and change the time of files located outside a writable directory. Only configurations using "mod_site_misc", which is not enabled by default, and where the attacker has write access to a directory, are vulnerable to this issue, which has been assigned CVE-2010-3867. More details can be found at http://bugs.proftpd.org/show_bug.cgi?id=3519

This update also fixes an issue with SQLite authentication and adds a new module "mod_geoip", which can be used to look up geographical information on connecting clients and use that to set access controls for the server.
