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"
