Date: January 27, 2008

ID: 200801-13:02


Synopsis

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

-------------------------------------------------------------------
 Package         /  Vulnerable  /                       Unaffected
-------------------------------------------------------------------

1 net-irc/ngircd < 0.10.4 >= 0.10.4

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 &quot;&gt;=net-irc/ngircd-0.10.4&quot;
