ngIRCd does not properly sanitize commands sent by users, allowing for
a Denial of Service.
Background
==========
ngIRCd is a free open source daemon for Internet Relay Chat (IRC).
Affected packages
=================

Description
===========

check the number of parameters, referencing an invalid pointer if no
channel is supplied.
Impact

A remote attacker can exploit this vulnerability to crash the ngIRCd
daemon.
Workaround
==========
There is no known workaround at this time.
