Severity: Normal
Title: InspIRCd: Denial of Service
Date: May 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
-------------------------------------------------------------------

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"
