Synopsis ========
ngIRCd is vulnerable to a buffer overflow that can be used to crash the daemon and possibly execute arbitrary code.
Background ==========
ngIRCd is a free open source daemon for Internet Relay Chat (IRC).
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-irc/ngircd < 0.8.2 >= 0.8.2
Description ===========
Florian Westphal discovered a buffer overflow caused by an integer underflow in the Lists_MakeMask() function of lists.c.
Impact ======
A remote attacker can exploit this buffer overflow to crash the ngIRCd daemon and possibly execute arbitrary code with the rights of the ngIRCd daemon process.
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-0.8.2"
