Conectiva Linux Advisory: proftpdSep 30, 2003, 20:58 (0 Talkback[s])
CONECTIVA LINUX SECURITY ANNOUNCEMENT
ISS X-Force has discovered a vulnerability in the way proftpd (versions >= 1.2.7) handles incoming ASCII file transfers. An attacker who is able to upload and download the same file can exploit this vulnerability to execute arbitrary code with root privileges.
The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2003-0831 to this issue.
Please note that after the upgrade the proftpd process will be automatically restarted if it is already running. It is recommended that administrators shut down all current connections (which will be using the vulnerable copy) to avoid a possible abuse by currently connected users.
