ProFTPD is a highly configurable FTP (File Transfer Protocol) server for Unix that allows for per-directory access restrictions, easy configuration of virtual FTP servers, and support for multiple authentication mechanisms. A flaw exists in the ProFTPD component that handles incoming ASCII file transfers. Impact: An attacker capable of uploading files to the vulnerable system can trigger a buffer overflow and execute arbitrary code to gain complete control of the system. Attackers may use this vulnerability to destroy, steal, or manipulate data on vulnerable FTP sites. Affected Versions: ProFTPD 1.2.7 ProFTPD 1.2.8 ProFTPD 1.2.8rc1 ProFTPD 1.2.8rc2 ProFTPD 1.2.9rc1 ProFTPD 1.2.9rc2 Note: Versions previous to version 1.2.7 may also be vulnerable.
