The remote host is missing an update for the 'WU-FTPD' package(s) announced via the SSA:2003-259-03 advisory. Upgraded WU-FTPD packages are available for Slackware 9.0 and -current. Fixed a problem where an attacker could use a specially crafted filename in conjunction with WU-FTPD's conversion feature to execute arbitrary commands. MAIL_ADMIN feature has been found to be insecure and disabled. It is not recommended to deploy WU-FTPD in situations where security is required

archives) to execute arbitrary commands on the server.

In addition, a MAIL_ADMIN which has been found to be insecure has
been disabled.

We do not recommend deploying WU-FTPD in situations where security
is required.


Here are the details from the Slackware 9.0 ChangeLog:
+--------------------------+
Tue Sep 23 14:43:10 PDT 2003
pasture/dontuse/wu-ftpd/wu-ftpd-2.6.2-i486-3.tgz: Fixed a security problem in
 /etc/ftpconversions (CVE-1999-0997). There's also another hole in wu-ftpd
 which may be triggered if the MAIL_ADMIN feature (notifies the admin of
 anonymous uploads) is used, so MAIL_ADMIN has been disabled in this build.
 Also note that we've moved this from /pasture to /pasture/dontuse, which
 should tell you something.
 (* Security fix *)
