"Upgraded WU-FTPD packages are available for Slackware 9.0 and -
-current. These fix a problem where an attacker could use a specially
crafted filename in conjunction with WU-FTPD's conversion feature
(mostly used to compress files, or produce tar 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."
