Hi all,
Just FYI, here is what was posted to the MySQL list from the MySQL
author regarding the DoS attack.

This never was fatal (only VERY annoying) for MySQL 3.20 ! MySQL has
a timeout of 30 seconds for each read from the client. This means
that the 'hang' only lasts 30 seconds for MySQL.
MySQL 3.21.26 and below has the same problem.
>From the changelog of 3.21.27 (I am compiling a distribution just now):
* Changed connect timeout to 3 seconds to make it somewhat harder
for crackers to kill mysqld trough telnet + TCP/IP.
Yours,
Monty
