ngIRCd: Denial of Service — GLSA 200801-13

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

Affected Packages

net-irc/ngircd on all architectures
Affected versions < 0.10.4
Unaffected versions >= 0.10.4

Background

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

Description

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.

Impact

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

Workaround

There is no known workaround at this time.

Resolution

All ngIRCd users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-irc/ngircd-0.10.4"
