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 ">=net-irc/ngircd-0.10.4"
