This was fixed in the source tree last night, and will be in the 4.0.9 release, which is being built as this is being written, and released ASAP.Description: MySQL 4.0.8, both compiled my me and the official release version crashes whenever receiving a network connection from a system without a DNS entry. Connecting from a system that resolves on reverse (eithor from DNS or a local hosts file entry) works find. This system is a Slackware 8.1 install with all currect updates. I do not know if this is a mysqld internal thing or some interaction with the system resolver in glibc 2.2.5, as unfort even a staticly compiled glibc binary uses the system resolver.This of course concerns me, there is a large potential for remote DoS here. How-To-Repeat: Install 4.0.8, run the install db script and fire it up. Attempt to connect from a host that will not reverse resolve. Even a telnet to port 3306 crashed the daemon. The dump from mysqld is included at the bottom of the message.
