Gentoo Linux Security Advisory

Title: ngIRCd: Denial of Service (GLSA 200801-13)
Severity: normal
Exploitable: remote
Date: January 27, 2008
Bug(s): #204834
ID: 200801-13

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: net-irc/ngircd
Vulnerable: < 0.10.4
Unaffected: >= 0.10.4
Architectures: All supported architectures


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


References
