DESCRIPTION
"wu-ftpd" is one of the ftp servers shipped with Conectiva Linux and
many other distributions.

 This is a follow-up to the CLSA-2001:442 announcement, where a
critical security problem was fixed. The wu-ftpd developers now
released[1] an official fix for that problem, but with two additional
corrections:
- format string fixes: some new format string bugs have been
patched;
- additional checks: null-pointer checks have been added to some
parts of the code.

 These two new fixes, as well as another one related to PASV mode[2]
(not security related), have been applied to the updated packages
presented through this advisory.


SOLUTION
It is recommended that all wu-ftpd users apply the update.
