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"
