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.
