PACKAGE : proftpd
SUMMARY : Remote vulnerability
DATE : 2003-09-29 15:03:00
ID : CLA-2003:750

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.
