Hmm.

The issue was scheduled to be made public at 12:00 pm EDT today.
Daniel Harris <dannyboy at FreeBSD.org> committed the fix to the FreeBSD
Ports Collection around 12:07 pm EDT today.

This issue will be rolled into the next FreeBSD Security Notice
(probably Monday --- serious problems like this tend to `trigger' a
notice).

If you want to bitch at someone, bitch at the wu-ftpd.org guys for
ignoring the reported bug for two months.

Cheers,
