Synopsis
========

A buffer overflow in InspIRCd allows remote attackers to cause a Denial
of Service.

Background
==========

InspIRCd (Inspire IRCd) is a modular C++ IRC daemon.

Affected packages
=================

    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  net-irc/inspircd      < 1.1.19                          >= 1.1.19

Description
===========

The "namesx" and "uhnames" modules do not properly validate
 network
input, leading to a buffer overflow.

Impact
======

A remote attacker can send specially crafted IRC commands to the
server, causing a Denial of Service.

Workaround
==========

Unload the "uhnames" module in the InspIRCd configuration.

Resolution
==========

All InspIRCd users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-irc/inspircd-1.1.19"
