Conectiva Linux Advisory: proftpd

Sep 30, 2003, 20:58 (0 Talkback[s])

CONECTIVA LINUX SECURITY ANNOUNCEMENT
PACKAGE : proftpd
SUMMARY : Remote vulnerability
DATE : 2003-09-29 15:03:00
ID : CLA-2003:750
RELEVANT RELEASES : 9

DESCRIPTION
ProFTPD is a highly configurable FTP daemon written from scratch for Unix and Unix-like operating systems.

ISS X-Force has discovered a vulnerability[1] 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[2].

SOLUTION
All proftpd users should upgrade.

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.
