-------------------------------------------------------------------------------- Fedora EPEL Update Notification FEDORA-EPEL-2011-0093 2011-01-20 06:04:09 -------------------------------------------------------------------------------- Name : proftpd Product : Fedora EPEL 4 Version : 1.3.3d 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 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. -------------------------------------------------------------------------------- References: [ 1 ] Bug #670170 - CVE-2010-4652 ProFTPD (mod_sql): Heap-based buffer overflow by processing certain usernames, when mod_sql module enabled https://bugzilla.redhat.com/show_bug.cgi?id=670170 -------------------------------------------------------------------------------- This update can be installed with the "yum" update programs.
