Title:	InspIRCd: Denial of Service
Date:	05/09/2008
Bugs:	#215704
ID:	200805-08

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	Architecture(s)
net-irc/inspircd	< 1.1.19	>= 1.1.19	All supported architectures

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"
