The remote host is running a version of ircd which may be vulnerable
to a format string attack.

An attacker may use this flaw to execute arbitrary code on this
host, or simply to disable this service remotely.

Solution : Upgrade to one of the following IRC daemon :
	andromede.net AndromedeIRCd 1.2.4
	DALnet Bahamut IRCd 1.4.36
	digatech digatech IRCd 1.2.2
	methane methane IRCd 0.1.2
