Corsaire Security Advisory - Netopia Timbuktu remote buffer overflow issue
-- Corsaire Security Advisory --
Title: Netopia Timbuktu remote buffer overflow issue
Date: 20.07.04
Application: Timbuktu v7.0.3
Environment: Mac OS X (10.1, 10.2, 10.3)
Author: Stephen de Vries [stephen.de.vries@xxxxxxxxxxxx]
Audience: General release
Reference: c040720-001
-- Scope --
The aim of this document is to define a vulnerability in the Timbuktu
product for Mac OS X, as supplied by Netopia [1], that allows a remote
attacker to crash the application and effectively deny service to
legitimate users.
-- History --
Discovered: 20.07.04
Vendor notified: 27.08.04
Document released: 19.11.04
-- Overview --
The Timbuktu software is shipped as a client/server application that
allows remote users to access the desktop of a host system. The server
component of this application is vulnerable to a remote buffer overflow
vulnerability that, when exploited, causes the server process to crash.
-- Analysis --
The server process runs with root privileges on the host Mac OS X and
listens for client connections on TCP port 407. By making a number of
concurrent connections to this port and repeatedly sending a particular
string of data, a memory buffer is overwritten and the server process
crashes.
-- Recommendations --
Upgrade to version v7.0.4 of the Timbuktu application.
-- CVE --
The Common Vulnerabilities and Exposures (CVE) project has assigned the
name CAN-2004-0810 to this issue. This is a candidate for inclusion in
the CVE list (http://cve.mitre.org), which standardises names for
security problems.
