ngIRCd does not properly sanitize commands sent by users, allowing for a Denial of Service.

2.  Impact Information


ngIRCd is a free open source daemon for Internet Relay Chat (IRC).


The IRC_PART() function in the file irc-channel.c does not properly check the number of parameters, referencing an invalid pointer if no channel is supplied.


A remote attacker can exploit this vulnerability to crash the ngIRCd daemon.

3.  Resolution Information


There is no known workaround at this time.


All ngIRCd users should upgrade to the latest version:
