[slackware-security] WU-FTPD Security Advisory (SSA:2003-259-03)

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.

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 *) +--------------------------+
