Package: wu-ftpd (wu-ftpd-academ)
Vulnerability: remote root exploit
Debian-specific: no

The version of wu-ftpd distributed in Debian GNU/Linux 2.1 (a.k.a. slink),
as well as in the frozen (potato) and unstable (woody) distributions, is
vulnerable to a remote root compromise.  The default configuration in all
current Debian packages prevents the currently available exploits in the
case of anonymous access, although local users could still possibly
compromise the server.

This has been fixed in versions 2.4.2.16-13.1 (for slink) and 2.6.0-5.1 (for
potato and woody), and we recommend that you update your wu-ftpd-academ (for
slink) or wu-ftpd (for potato and woody) package immediately.
