The remote host is vulnerable to a Denial of Service (DoS) attack.
The remote host is running an ignitionServer IRC server. This version of ignitionServer is reported to be prone to a remote remote denial of service in the way that the server handles channel locking. Specifically, a non-operator can create a locked channel which cannot be unlocked by an authorized operator. The only way to clear the channel would be to reboot the server. This can cause a loss of availability.
Upgrade to version 0.3.6p1 or higher.
