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
